73-87 Suspension swap

[777ralph]

I'm swapping the suspension, power brake setup, and steering from an 82 GMC halfton to my 64 Chevy shortbox. Here's the victim:

And there goes the donor:

The front bumper is 9 inches off the ground right now, and hopefully will be about the same when I'm done (the roads here suck). The previous owner torched two and three-quarter coils off to lower the front. I'm hoping to end up in the same place with one coil cut off the donor springs, and a set of 2 1/2" dropped Belltch spindles. Sound about right? I got the spindles off Kijiji, and the six bolt discs and calipers and stuff for a smokin deal from our friends at CPP.
I read somewhere that to use the 73-87 lower A arms you had to drill out the Ubolt holes in the crossmember for the larger, newer Ubolts. Nope. Bolts right up with the 64 Ubolts, though they do look puny compared to the newer ones.

For the power steering conversion I'm going to look at grafting a bit of the 82 frame onto the 64 to mount the steering box. Anybody done it? Probably the easier option would be to call up Captainfab for one of his adapters, but I wanted to look at the grafting possibility first.
I got the A arms in today, and I'll continue this thread when I get more done during the holidays.
