Re: 1966 Height conundrum
I’ve come to the conclusion that the listed bumper heights in the assembly manual, on the GM Reference CD and on the GM Heritage website are wrong. Absolutely no way they could be correct.
I’ve got 3” lowering springs in the rear and I’m at 15.75”. All three of these sources say it should be 11”.
There isn’t enough room between my axle tube and the frame, even without the bump stops, to get the rear bumper to 11”.
