TB1, thanks for posting your experiences! All your viewers appreciate it: I certainly do!
I've been considering the TKX since last fall for my '64 GTO. I'm in the US between DC and Baltimore and have been in touch with Silver Sport, who advertises, I think, over 25 custom shifter adapters. So far, they are my supplier of choice.
I understand that we need to move the transmission crossmember back, but is it still the correct height? I don't want to mess up my pinion angle. Please let us know.
Again, thank you for sharing your upgrade!
