Hey Guys, I'm doing up a half tub model in CAD but my tub is rotted pretty bad so I need some help with measurements. When I get this done I'm going to post some full size patterns and blueprints for a nice home brew tub. I have a 1982 BJ42 so I need measurements from a unit with the same tub. Someone crudely replaced the rear fenders in my unit so I need the height, width and the angle at the front of the fenders. I would like to have some measurements for the location and radius of the s-bend at the bottom rear corner of the quarter fenders (Where it curves up to clear the bumper). I need the height difference as well as the location of the beginning of the first bend relative to the door sill. Also, if someone could take some pictures of the fender reinforcements from under the fender that would be great as I'll need to model up new supports.

Sorry 'bout that Wally. Ran out of time and forgot what I had to measure.

But I'm on my way back up to the shop in about 10 minutes. You'll definitely have some this evening.

Here are some measurements off our 1979 FJ-40. Should be the same body for you....

Outside tub to outside tub: 64"

The tailgate opening is 41 3/4" wide (this is where a door would fit), but the actual opening is 41 1/8" wide (this is the widest box you could slide through there). Look carefully at your corner posts and you'll see the difference...

The innder fenders at 7 7/16" tall (above the floor, to the flat section of the fender well--the raised ridges are taller), and 11 7/16" wide (that's flange to corner.

I couldn't think of a good way to measure the radius of the curve, but the flat section to the curve tangent is 6" from the vertical flange of the corner post (the door opening).

this is a good idea surprised no one has got back to you maybe because it a bj 42 and not a fj40 would the sizes be the same

Yeah, the lack of interest really has me scratching my head. Bet people will be happy when the model is done though. :rolleyes:

My floor boards are rusted to hell as well so I think I'm going to model the whole tub. I'll be doing the frame rails as well when the old tub comes off.

That's awesome Dan, thank you! I hope you don't mind, I may harass you for some more measurements and maybe have you take a look at my model when I'm done. Do you have a Digital camera? Any chance you could take some pics of the inside of the rear wheel wells for me?

Easily. Any particulars? Since the quarters are currently removed for rust repair, I have TONS of access to stuff right now. I *might* be welding the quarters back on next week though.

Well, since I'm using flat steel for the floor I have to build a sub-frame of sorts for the rear half of the tub. What I need to see are the stiffeners/supports for the rear fenders. I'm not sure if they are incorporated into the roll bar or not and I would like to know how all that works. I think it would be a good idea to have the roll bar bolt to the fender supports.

Other than that, I don't know what else I would need photo's of.
 
The fender supports also incorporate the captive nuts for the roll bar.

I'll get clear pics of those for you, and measurements. Really easy since I've removed my fender supports (much of the rust was between the fenders and fender supports). I am not going to reinstall the front ones, as I am using a Metal Tech Jackson Cage instead of the original, and the front frame supports are going to be replaced by frame ties up front. But I'm going to keep the rear supports for the back of the cage.

I think you should measure the inside lip of the top tub which for me has always been 62 1/4 to 62 1/2. And a measurment from the top of the right door post to the left rear amby door post and visa versa , OR the top will not go on without considerable perswation.
 
I've been out of town for 2 weeks and haven't really been working on the model much but I'm home now and I should be able to get some stuff done this weekend/week. I'll definitely be looking for some input from you guys.

great effort!
If you need more, I can try get some measurements. Not sure how good I will be on the fancy ones, but I'll give it go.

Thanks a lot! :) I'll let you know if I need anything.

Awesome, thanks dan. I'm looking forward to seeing the pics. I realized that I also need an angle for the front of the rear wheel wells. That or a top measurement and a bottom measurement.

I agree. I have a top and may try to line stuff up with it on the body. We'll see how it goes. At the very least I can measure my top and make sure everything is hunky dory.
