Yes, the '73-'87 front and rear ends are wide for an AD truck. They fit fine in mid-'60s trucks.
I'm still wrassling with the wheel question. I was told in another thread that wheels from '93 3/4 ton had a lot of backset, but when I called an all-GM truck wrecking yard the fellow there said no. I guess I'll have to go there with a tape measure next time I'm in the big city.
Since I'm swapping both ends for later model stuff, I can use the same wheels all the way around once I find them. If I can't find a stock wheel that works, I'll have wheels built by Stockton Wheel. They can do pretty much anything, for a price.
