Hey Phat - if you're gonna fix it up, drop a stinkin' V8 in that baby!
I gotta respectfully argue with you on the front track width..
I got the stock rims up front on mine (6" backspace) and they fit great. I get the full turning radius and the tires are about 2" inside the wheel opening. I tried mounting some rims with 4" backspacing and there's no way I can corner without 'em rubbing. Mind you, mine sits real low, the top of the tire is an inch or two above the wheel opening. I'm lifting the front of the cab a bit while I'm doing the floor so hopefully I can use the 4" backspace rims (so I only haveta carry one spare). The tires sit pretty much flush with the wheel opening then.
For the rear track width, I just swapped in the 4" backspaced rims and it clears the inner tub OK.
Now, there may be some differences here - you have a 2nd gen frame, I used a 1st gen. 2nd gen apparently only use a 4" backspacing, I don't know if the track width is wider or not. And I'm guessing 'Burb running gear is the same as pickups.
