Rear body mounts

[pro1955]

Hi guys, I just bought a 1956 stepside, I'm replacing the rear cab mounts. On both sides the bolts are broke off in the cab. Is there a way to access them by removing the fuel tank? Thanks, Glenn.

Yes, remove the tank and you will see the captured nuts. If you are lucky a good soaking with WD40, etc. and an easy out will get them out. If not you can replace the nut assembly.

Thank you for the reply, I was looking at it tonight and one of the captured nuts isn't anymore. I'm guessing that I will have to fix that first, can you just use a nut and washer or weld another nut?

The rear cab mounts on my 57 were just bolts that went through the cab and frame with nuts on them.
Are the earlier ones different?

Bolt and nut with lock washers will work, as well as spot welding. The caged nut had a little movement to help with adjusting the cab square on the frame. It sounds like Kim's got removed somewhere, the assembly manual shows the caged nuts too.

Here's a link to a cab mounting kit for 55-59 cabs. This is the one I got to put my cab back on. It has bolt and nut sets for the fron and rear of the cab. When I first dis-assembled my truck this is what the factory set looked like.
I've had 2 different cabs at one time and neither one had caged nuts for the cab mounts.

That is the same kit I have, one bolt is broke off the other one just spins. Looks like I have some fab work ahead of me, the left side rocker panel is bent also. I was thinking of putting the tank under the bed, now might be a good time. Just don't want to tear it all apart summer is coming. Thanks for all the replies. Glenn.

I found a photo that shows my 59 rear mount caged nut. Maybe they changed in 58?
