TF spring shackle problem

[RRinWT]

Hey guys!

My name is Rob and I've been lurking for a month or so looking at the build threads and general questions, trying to get back up to speed on wrenching on these old trucks. It's been 10 years since my last build and I have forgotten a few things.

My first question is, on the rear springs, how in the @#%% do you get the spring eye bolt all the way out? I removed the tapered locking pin and drove the bolt back but it is hitting the frame. The shackles are off on the back end. Do I need to unbolt the springs from the axel?

Second, the left rear shackle bolt is rusted in place and broke in half in the frame bracket. The piece of the bolt on the inside came out with no problem. The rusted in stub, fortunately, is sticking to the outside. Anyone know how to get that thing out? I tried a 24" pipe wrench and it wouldn't budge. Should I try heating the frame bracket and see if it'll break loose?

The frame is a '58. Is the threaded sleeve inside the frame bracket replaceable? I'm looking at a picture of a shackle kit and it appears to come with 2 threaded sleeves. One for the spring eye and one for the frame bracket?

I'll start a build thread so everyone can see the strange combination of 55-59 Chevy and GMC parts I using.

Thanks!
