[fast75]

can any of you guys give me some info on rear-end length, hub face to hub face, back spacing and tire size?, and any problems that may jump up and bite me in the azz in the process of doing this....................Thanks..........

What are you looking to accomplish? What size wheel/tire are you trying to fit?

i want to put 33x21.5x15 tires on 15x15 rims inside the fender wells. i know i'll have to back half the truck. i'll use either mark williams or chris alston rails. thanks, Lee...................

Here's one that's close. It belongs to forum member CoggedBelt75- Rears are Hoosier Pro-Street Radials 31x18.5R15L on Convo-Pro 15x14 with a 4 1/2" backspace on a 44" flange to flange 12 bolt rear end.

Really don't think you would need to back half it, but if you do, would the added expense be worth less than an 1" in tread width? Here's a look under mine. It's a stock frame notched just above the 44" flange to flange axle housing with Ford ends, Moser axles, spool, 4.56, Koni coil overs, 4-linked, Wilwood disc kit, . With the 14.5" tread street tires I have 3" from sidewall to inside of wheelwell lip. My slicks for burnouts are Goodyear Eagle 33x16x15 mounted on steel wheels with 15x14 and 4 1/2" backspacing. They are 16.3" tread which is 1.8" wider on the tread but the sectional in not as wide as the radials so it is about 1/2" from the lip. There is a very slight scuff mark on the frame with the slicks. Hope this helps you and good luck with your project!!! Joe

thats one sweet set up. i had heard that i could do a poor man's tub job by just swapping the spring hangers to the the inside of the frame rails and boxing it in. your set up looks a whole lot better, no more leaf springs. it doesn't seem like there would be any loss of frame integrity either. that was a big concern. well crap, off comes the bed again........lol. Coggedbelt75 and N2TRUX are my new hero's Thanks guys........................
