Charlie,
It is very good to see everyone commenting on how cool your Yenko is, and making comments about it being the best Yenko ever . . . even though it was sent back many years later to Yenko so they could upgrade it.
We have people here sending their GMMG cars back to us for a Phase 2 or Phase 3 upgrade all the time. I tell GMMG owners that they can, at any time, while they own their car, send it back to us for an engine upgrade package, (phase 2 or 3 only). Your car is like one of those cars that was sent back.
We do have a lot of people that ask me to NOT do that because they think it is not fair . . . Not sure why, because they can do the same to their car. I will be giving your name and late night number to all those guys that call and ask me not to do that . . . and you can tell them why they should . . .
I like the '67 vinyl top . . . it looks natural and the original '69 vinyl tops look like a bad haircut 1/2" above the ears.
