I am lowering my 71 chevelle, 2" in the rear, 2" in the front, and I cant find anybody with lowering shocks. Can any one help?

Shocks do not lower your car, but drop spindles and springs do.

I used the Edelbrock - Eibach springs and shocks and have been happy with the combo dropped 1.5-2" looks good.

I suspect that you can get by with the standard type of shock, as the full jounce position is determined by the jounce bumper, not by the springs you have. If you have not modified the jounce bumpers, you should be OK.
