... and a couple close ups...

As you can see I incorporated an additional stainless steel heat shield over the first catalyst. It sits below the passenger footwell so I wanted to direct the heat elsewhere as much as possible. I'm also using Thermo-tec heat and sound deflecting material (dynamat) on the inside. The rest of the exhuast is either far from the floor or so far back that I deemed heat shielding unnecessary.

Though the truck is titled as the original 1972 FJ40 I retained two functional catalysts anyway. Why? Becuase I could. High flow cats don't hurt performance, keep the emissions reasonable and keep the law off my back. Good enough for me.

Vince has a lot of good ideas, one of which was to bring the exhaust straight out the back on the driver side. I couldn't get my head around this and ignored him. It was a real PITA and I had to hard mount the exhaust back here because the clearances are so tight. (I had to trim out a pinch weld in the body and cut down a body mount just to get it in there) Nonetheless my stubborness prevailed and my exhaust exits on the rear passenger corner. I chose passenger side over driver side exit so that it would be quieter (imagine driving next to a Jersey Barrier with the exhaust exiting on the driver side - lots of reflected noise). I also didn't want the rear exit because it would then pump fumes in your face if the engine is running and you're unloading or otherwise accessing the rear cargo area.

As I'm sure Vince will one day point out, I have directed the exhaust into the face of the poor soul destined to operate the rear winch instead...

While I'm on the subject of ignoring Vince, lets talk about electrical wiring... Vince helped me pin out and pare down the 80 harness. He suggested that we clip the plugs off and tape up the wires - just to make sure we didn't later decide that we wanted to use those circuits for something else (or worse still that we'd mistakenly cut out the wrong wire). Again, a good idea, totally ignored.

The harness was huge, and even in pared down form barely fits in the extremely limited dash space of the 40.

I insisted we strip the harness down to bare minimums. This took twice as long, increases the odds of a mistake, and has the side benefit of spending hours trying to scrub the goo from 10 year old electrical tape off of everything you've touched that day.

I'm happy with it.

One more topic before we get to the interior: Fuel tank.

The stock 80 tank will not fit with the drivetrain relocated. I had plans to build a completely custom stainless steel tank but ran low on time and cut up the 80 tank instead. I basically cut it in half, turned it sideways and capped it with stainless steel. This keeps the stock fuel pump/sender, filler neck and other assorted requirements like the closed venting system.

 

[IPOR]

The problem is that only nets me 15.5 gallons. I know, better than a stock 40... but this is not a stock 40, so like everything else on the truck I had to re-invent the wheel. I added an extension to the front of the tank that gives me another 3.5 gallon capacity for a total of approximately 19 gallons. Much better. I retained the baffles from the discarded portion of the 80 tank and incorporated them into the new extension. I also stripped and drilled the front of the tank to be used as a baffle.
Sorry guys, I couldn't find a picture showing the extension after install, but you can see it in the pics of the tank installed in the truck - later.

Toyota mounted fuel tanks either in the body or attached to the bottom of the body. I definitely didn't want it inside - thus the late model floor pan on the early model truck. I also didn't want it attached to the body. When I roll off the side of a mountain I want the body (with me in it) to go one way and the fuel to go the other! Ha... kidding. Seriously though i didn't want the body to carry the weight of the fuel tank. Not that there's anything wrong with that but the body panels I used to fabricate the body are OEM stampings that were not designed to carry the weight of the tank where this tank is mounted. Since I was designing a heavy duty skid plate and mounting system I mounted the tank to the frame instead.

 

[IPOR]

In those last couple pics you can see a slightly modified version of our FZJ80 skid plate (using countersunk hardware - the trans mount will be done this way as well for a totally smooth belly pan) and the front extension housing on the tank which comes forward above the crossmember/skid. Also of note: the one hole in the fuel tank skid that is larger and offset to one side is centered on the fuel tank drain plug - IOW, it's supposed to be that way.

The framework is 1.5" x .120 HREW and the mounting bolts will also be countersunk at the frame rail. There are rubber isolators between the framework and tank. The tank is held in place with steel straps. The skid plate is only 11" wide and even with the bottom of the frame rail so unlikely to ever be touched. Mindful of the gluttony of steel in this truck I thought I'd save a pound here and use 1/8" plate.

This is it for now, I need to get back to work so the body can go to paint today...

Looking good.

We usually put the flex pimp fairly close to the engine were the most movement occurs.



Don't ya just hate those exhaust flanges, the nut and bolt are so close to the weld., Wish they built a bigger flange with a small insert.

So do I, but in this case I didn't have enough room. The front half of the exhaust is on flexible hangers and I hope it will move with the motor like a standard exhaust. It's only the rear that I had to hard mount.

So I put some rock rails on the truck today. This has been an ongoing debate for me since I first started the project. I like the truck without any rails, but know that it will be easier on the sheetmetal with rails and that having a uniform surface to slide on is more effective than getting hung up on a fender. With the rails I have a straight line down the side... which should be more effective... but I think it looks terrible.

My son (6) likes them, what do you think?

couple other views for you...

Keep or cut off?

all I can say is that while the pictures are good....it is even sweeter in person


IronPig does some amazing work - makes my crap look like...er...well...crap

I would keep them, they look good. On any other rig I don't think they would look right, but with your widened front fenders and rear flares they fit nicely.

 

[Waggoner5]

Keep them.

Way to go bud....... going to be ready for Moab???

Let Vince off work & listen to him more......

I would keep them, they look good !

making the passage from fender to body fluent (I hope you understand what I mean ...)

but are they welded to the body ? Will that be strong enough to use them as sliders or for a jack ?

Why did you not build them frame mounted

I do understand, in fact I think you said it better than I could have. I'm glad to have some positive reinforcement on the idea!

They are welded to the body, but the rockers are part of the subframe for the roll cage and tie in to the frame with it. So in essence they are frame mounted.

Ha! I don't have to worry about any more good ideas coming from that guy. He and Amy had their first baby last week. He's going to start my "no-sleep" regimine now.

Ready in 7 weeks? Not really sure... but I think so. It may depend largely on my painter. I was supposed to have the body to him a week ago. Instead i brought him all of the other panels two weeks ago but even so he still hasn't had a chance to get to them. He says no problem but I see his workload and I am less optimistic... Even after it comes back from paint I need to finish the electrical wiring, brake and fuel line routing and of course reassemble the body.
