Okay, so you agree with me completely not. Got it. What you are really saying, probably without realizing it, is that a brand new coil over - without adding any structural additions to the front end - is superior to doing nothing to a 40+ year old car. Okay, I can 'agree' with that. Of course, as I said in other posts, or at least alluded to, one 45 year old car can be very different than another 45 year old car. They also changed between 64 and 77 - upper control arms, idler arms, sway bar mounts, T-bars, spindels ... and you are right in 'agreeing' with me, in that a 1969 A-body was NOT designed with 18" wheels, 40 series tires, and 2X the stiffness in T-bars. But it was not designed to use coil overs either. I did state more than once that it is very possible that the cars had built into them enough structural capacity to deal with the new systems to which you refer. It is possible that they had not as well. Check back with us in 45 years.
