[QUOTE=Adams' Apple]Soak that puppy REAL GUD, then drive it around a while. The combination of penetrant and up/down motion of the t-arms might just break that thing loose. In order to get the best penetration of the PB Blaster, you may want to remove the shims(be sure to mark them and keep them in the same location) on either side of the t-arm so you can get directly at the bolt as it passes thru the bushing.
I've never had one that was seized up like that, but I've heard stories...plenty of them!
You might want to consider using an air hammer on the outer end...
I wouldn't recommend a smoke wrench for heating it up, but some folks have done that, too.
If all else fails, there's only one final solution..."sawz-all" [/QUOTE]

i used a saws-all on the '76 and was rather a simple task... had to use a long blade, fine toothed.  Took about 10-15 minutes and had both trailing arms out, took a smaller sized bolt to knock out the rest of the bolt.

Jim, if I have to go that route, is there any trick to getting the new bolt back in and through the T arms with the little bitty bit of work room there is?

I heard of this trick from a maintenance man were I work. I have not had the opportunity to try it so I don't know if it will work or not; but it is fairly simple and may be worth a try. Heat the nut and bolt up and melt wax over them. The wax will soak in to the threads and you should be able to loosen it. Let me know if you try it.

I cut mine out as well; that was the easy part - the reinstall took the most time on my setup. and yes I thought about removing the body or at least lifting it off the mounts for more room - it was a passsing thought once I weighed all the work involved.

I had forgotten about that but saw that done many years ago at at local shop when I was a youngster.  If all else fails, Ill raid the Christmas candles.  Thanks.

Keep us posted if it works. My hands were destroyed from that job. The worst job is this and the power brake booster. Another great job is stainless steel brake line install without the body off....

We really didn't have much trouble getting the new bolts back into the trailing arms... it did take 2 of us to do it though,  one(me) holding the trailing arm somewhat aligned, and a buddy starting the bolt in, and then taking a hammer  to it(we had it up on a lift, so, it was about head level, that did make a ton of difference... but, once the bolt was started, just took a few good whacks and it was in place...

I forgot to mention the "JOY" of replacing the fuel lines with the body on Working on our cars can create words that you never knew could flow from your mouth. Good luck with the trailing arms........and thanx again!
