Leaf spring relocation - shackles to frame
I agree that stock tub's will fit a 275, no problem, that's why I mentioned the backspacing. The axle I shortened is 48" long now, so it's 4 5/8" shorter then stock, my wheels only come in 4 1/2" backspacing, so that's why they were so tight. And, yes to your point every car is a little different, my buddy had 245's on the back of his 68 dart, with stock everything except they were small bolt ralleye wheel's. He had to jack car up on frame and let the axle hang to get them on, but they fit lol. Holy crap those tires are tight on that red 69 in first picture! I love the spring relocation I did to mine, have ton's of room now, I was afraid of wiping out a quarter panel every time I hit a high speed turn so I solved that problem.
