That's a stellar longhorn!

Comments on the wheel/wheelwell spacing:

1) Tires have a lot to do with the whole scenario. A 10" wide wheel can take a 275 tire or a 12.5" tire. A 10" wide 16" tall wheel can take 35" tall tires or 28" tall tires, so don't forget to think about tires!

2) a few things I recently learned about track width:

I have a '74 12 bolt with drums in my 67C20, and 17x9 ralleys with 5" bs on the rear (I look at it like I have 4" of "frontspace"), and I have 1.5" of space between tire and fenderwell.

In the front, I have factory style 5 lug discs, and 17x8 with 4" bs (or in my weird world, 4" of "frontspace"). This leaves me about 3/8" between tire and fenderwell.

I guess what I'm getting at hear is that first of all, with factory discs and a "wide" rear end (71' and up if I'm not mistaken), the front track width is wider than the front. Secondly, you can fit a 10" wide wheel with discs and 4" backspace if your truck is stock height (just don't go 40mph over speed bumps!). But, you'd probably be happier if you ran 8" wide wheel on a factory height, factory disc truck.

But, as usual, I could be completely wrong.
