On my 86 I had Strange double adj. but I did not have the car long enough to dial them in.
I have heard of Strange, QA-1, and Afco. Who has what and why. I am installing Mega-Bite Jr. uppers and lowers and want to better my 60' times with some nice adjustable shocks.
Let us know how it works out. I was thinking about the QA1's myself. I'm pretty sure some good shocks and an air bag in the right rear will let me get into the 1.7's
