difference between MP vs SS 002's/003" springs

Fairmont?
I grew up there graduated in 85.
As for the springs, they are kinda high in the rear so I added a 1" lowering block, for the money you cannot beat them.
If you order new u-bolts with the springs, just get them a little long, and order the blocks from Summit. I plan on removing the blocks after the car gets some miles on it.
Right now I have stock 15 x 7 with 4.25 bs on the rims with 275/60/15 rear tires and they clear with no issues using the lowering blocks.
Sorry to hear about the apple orchards. I guess it comes down to the almighty $$$$.
