I'm sorry, I don't have any window cranks. '67 & '68 are different. For my '68 I used Classic Headquarters cranks. Nice quality. I found the retaining clip slot was a little wider than my clip removal tool. Glad I checked before installing.
Camaro fender sale is pending. A gent from MI wants it and some other parts. Planning to connect mid-January. If deal falls apart I'll let you know.
