Ok '641/2-'66 restomod guys, need your help. I'm building a '65 GT, I'd like to fill those wheelwells (ESPECIALLY the rears) with more tire. I've seen it done (finished result), would really like some tips/tricks on the procedures, both for the fronts and the rears. The rears are doubled, correct? That's a lotta metal to bend without distorting the adjacent material (would seem to me). How did you guys do it? If it's a cut/trim/grind deal, will it weaken the fender without the structural lip?

We fit some good sized rubber under there without modifying the fenders. How big of tire are you thinking of?SteveW

Would love to squeeze 255/60R/15's back there... most likely on 15x8.5 Torq-Thrusts... probably 225's on the front, shouldn't be as big a deal as the rears, hua?

I might add: The Torq-Thrusts have a 3 3/4" backspacing... it could limit me, but I sure do like the stance of that wheel. The Vintage 45's have, what, a 4 3/8" bs? More attractive number, but the $$$ is not as attractive as the TT's. Besides, I'd rather have the sidewall of the 15" wheel (1/4 mile). I'm sure 'custom' backspacings are available, but this project is over-budget as it is (show me one that isn't).

I fit 235/60/15R they produce a diameter of 26.1 and I have no wheel rub. I also am running Adjustable Air Shocks on the rear, yet they are at the lowest height. In addition I was running 17's on the rear on one of my 65's and it's total diameter was about 28 maybe 29 inches, and it rubbed only on one side while the other was fine however they had a backspacing of about 4 inches which tucked the tires under the fender rather that sticking it out. My friend used metal snips to not cut the edge off but cut into then bend the metal back.Not that it matters to your question but what brand of tires were you thinking of getting? I am looking for tires myself. I am thinking about getting BFgoodrich Radial T/A's. ------------------

How short are the sections? Use anything special to roll them?

With stock wheelwells, you won't be able to use a 28" tire. It just WON'T work.To fit a 245/60/15 (largest you'll even think about with a stock wheelwell) everything will have to be perfect. The maximum backspace you can use is 4.5". I doubt you're going to get away with an 8" wheel. However, a 7" wheel with a 4.5" backspace will comfortably fit a 235/60/15. I believe those tires I used to run were 60's... maybe 70's, but I'm SURE about the 235/245 and the 4.5" backspace. I've since trimmed the front of the quarter panel out a couple inches and trimmed the lip to fit a 4.5" backspace 8" wheel with a 275/60/15. The front of the quarter had to be trimmed to fit this new 28" tire. The inside wheelhouse in the front got a little "work" with a big hammer as well. The 4.5" backspace works great with the big tire, but with my 28x9 Hoosier slicks, a 1/4" wheel spacer is needed. This is with a new Currie rear housing. The old 57-59 housing was a -tad- wider, and the spacers were not needed. Go figure. You will also want to be careful to make sure the housing is centered in the car. Most of those old cars have the housing shifted to one side... sometimes an inch or more. On some cars the U-bolts can loosened enough to slide the housing over enough to center it. Others need to have the holes in the perches re-drilled. If one side is rubbing and not the other, go check... I bet you'll find the axle is not properly centered. Centering it will often fix the rubbing problem. Good Luck! ------------------

Do you have the dimensions (width) of the one they built for you? Are your leafs in the stock location?
Currie is (conveniently) only about 5 miles from my place...

I am thinking about getting a 255/60/15r on my rear. Will that Fit? I do have air shocks to raise it. What dimension will be more restricted? The width or height? Will a 235/60/15r fit in the front?------------------
