My 1970 FJ40 Hard Top Build Thread

[Johnnynibert]

I'm also thinking about replacing the stock 3 speed with a Muncie SM420

 

[wngrog]

If you can find one it's a great simple swap to get low gears.

I bet folks still sell the adapter. You need your F bellhousing and your old Tcase.

 

[Johnnynibert]

Well I have a friend that just happens to have an SM420 10 spline and Advanced Adapters makes the kits to make it all work. It's just expensive. About $1500

 

[wngrog]

No. Those adapters are more like $200. Do the research by you want the simple one that goes to the "3 speed" case.

 

[Johnnynibert]

Got the original 1F motor out last night and the 1978 2F motor on the stand. It was a good day. Couldn't have done it without my son's help. Now to take the top, doors, fenders, and windshield off to remove and repair the body tub. While it's off I'll also be sanding and repainting the frame and axles and installing a 4 inch lift and the Narrow SS 34 inch tires.

 

[wngrog]

Good report

 

[Johnnynibert]

Now I'm just waiting for some help to move the body tub to the shed so I can sand and repaint the frame and axles. Before the body tub is repainted and put back on a 4 inch lift, new brake lines, a set of new body mount bushings and all the adapters to fit the G.M. muncie SM465 transmission to the stock transfer case and 2F will be installed. I have a lot of work ahead and it's going very slowly because I was laid off from the oilfield a month and a half ago and have yet to find a job.

 

[wngrog]

Good job

 

[Johnnynibert]

Finally got enough help to get the body off of the frame! Now to get it sand blasted and primed!

 

[Johnnynibert]

Where can I find a complete motor and trans mount kit with all the hardware?

 

[wngrog]

You mean to reinstall your old drivetrain of a V8?

Either can be found via Advance Adapters and Orangefj45 or Georg is the club contact for AA parts.

[onemanarmy]

might want to check the 'parting out' section in the classifieds to see if anyone has any 2F FJ40 parts

 

[Johnnynibert]

Well I replaced my 1F with a 2F but I'm keeping my stock 3 speed and transfer case so is there any difference in the F and 2F motor mounts?

 

[Johnnynibert]

Also will all of the 1F bolt ons, (intake/exhaust manifold, etc.) bolt on to the 2F?

 

[wngrog]

I think it is all different. Maybe on the motor mounts but exhaust all different.

 

[jrob]

I have a set of headers that I took off of my 2F, if you are interested. I only had them on there about a year, they are in good shape.

 

[Johnnynibert]

Are they the split headers? If so they supposedly won't work with my stock PTO winch

 

[Bodean]

Nope. 6 into one.

 

[Johnnynibert]

Well I'm a long any from needing it but how much would you want for it?

 

[Johnnynibert]

Since we are on the subject, I have been looking for the Offenhauser 4 bbl intake manifold for my 2F for 2 years now, with no luck.
