Need to know stat...m-body 8 1/4

You may want to look into a Ford Expolorer 8.8 too. I havent done it, but I hear they are very close. The only thing I see might not work is the spring perches may be designed for the isomeric(sp?) rubber mounted leaf springs. ALl that menas is the hole to align the rear on the spring bolt is like 1.25" in diameter, as opposed to 5." I took 1/8" thick washers, drilled the right hole size in them, and welded them into the larger holes. Works fine, the car's running 12.0s with a 530hp 418 now.
