What is the differance in the differnt models? I am trying to rebuild my suspension and lots of you have said good things about them. What are "Good ones"? I am looking for a fairly firm setup but not so stiff that I can't drive it on the road.

I'm using the Gas-A-Just, I love them, they offer a firm ride that I feel is just about right. Don't get me wrong, if I could afford it, my car would have Koni's on all four corners, but until that time I'm happy with my KYB Gas-A-Just shocks.

I just bought a set of four for my 70 and I had them before on my 67 and I've always liked the way they feel.

I don't think you can beat the ride of that shock for the price. They are like $26 each.
