70-72 body mounts to frame
While loosening up (or should I say breaking) the body mount bolts on my 71, I found that I had to cut small doors to access the two far rear ones because they would not give. The square nuts seem to be loose in a small cage that is welded down to the body.
Are the nuts suppose to be welded down also of do they move within there with the cage to keep them from spinning? I also believe this is the same setup on the two mounts under the doors. One other question..... the 71 Service Manual lists a total of four bolts on each side but I can only see three, the others seem to be just bushings resting on the frame. I found two forward (lower firewall), two under doors, and two far rear so far. thanks

Mine had the cages spin till they caught the frame.

i pull 20+ frames a year..some time double, and how i get around it is simple, and old bodyman sowed me and works 99.9% of the time, and rarely to i use penitrating oil, because i dont want to open the floor if dont have to....
good old manual ratchet....it either breaks loose, or breaks the bolt..putting an impact on it strips out the cage and they just spin and you are screwed..just nice and slow, continous pressure and out they come

Taking mine out, I came to the conclusion that the pads were added before the lower control arms were installed. No other good way to get to them.

The blue wrench works too.

Weird! Never knew that blue was better than chrome.

Even using a manual ratchet, I broke several mounts.
Here is a brief article on the repair. http://www.buickperformanceclub.com/...BodyMounts.htm |

Yes but you're not lucky enough to deal with 40 years of road salt hitting the undercarriage like we are up here

Yes, yes and yes. My car is a Wisconsin car and I got out 4 out of 6 of them and was very taken care of. And that in itself is an amazing feat.

When I did my '67 convert, I ended up breaking off both rear bolts. I think the factory cross threads a lot of them. They don't think anyone will ever want to unbolt them, so they don't care.

thanks I assume those nuts are not suppose to be welded down. It makes sense that they would design it that way so you had some room to play with when they dropped the body down at the factory.

A sawsall works well too - just go straight through the rubber and the bolt. I had four I had to cut through last week - took longer to run the cords.

I soak them in PB blaster the best I can and take them off by hand with a ratchet. Also I always tighten the bolt 1/8 turn first then back it out. I've snapped bolts that have rusted under the rubber bushings but the only cage nuts I have stripped were before I starting doing this and used the impact...

I've drilled an 1/8" hole thru the floor pan directly above the caged nut & spray it good w/PB blaster for several days thru the hole then try to remove the bolts. 9 out of 10 times they'll come out w/o issue.
