Spring Relocation without mini tub...

I moved my springs into the frame. I used the mopar kit as it was the cheapest. I only needed about 1.5 inchs, but the kit moves a minumum of 3 inches or nothing. I tried the offset shacle kit but it only moved the spring 3/8 of an inch. This is on a 65 Cuda. I now can run a 275 in the stock wheel well. My my rear rims are 17 X 9, +24mm offset with a 5.95 back space. I'm using a stock width 8 3/4 rear from a 69 dart.
