If you think a 67 is ignored you should try finding stuff for the 64.
I'm doing budget math in my head trying to figure out what I need to do to get bilsteins and the 1.030" Torsion bars to go with my super stock leaf springs. Might as well do polyspherical bushings and redo every bushing while I'm in there too.
The thing I like about bilsteins is that no matter what brand of car guys you talk to, mention bilsteins and you get the same "in awe" reaction.
