Somebody correct me if I am wrong , but I was looking at a set of Dougs in a car last week end.....slip fit tubes and mini starter required.
TTI's for some reason I am thinking the torsion bars need to be removed , or maybe just on one side to install.....I seem to recall reading this when i was shopping for a set.
I had Hooker Super Comps in an early A and one tube goes outside the fender well........not easy until you have done it a few times.
My last set was home made and with an AlterKtion and much of the inner fender removed , which opened up a whole new series of issues. :D
