1969 dana / yenko cooperative effort

[ceb]

I am looking for any information that might be available on a cooperative effort between Dana Chevrolet and Yenko Chevrolet in 1969. I have had numerous conversations with Warren D. on a California built Camaro that I presently own that was ordered on the west coast as a SS 350 and converted to big block at its inception. The car has an original BV rear (410 posi -- detroit gear -- high hp -- west coast) a no date code m21 4 speed and a replaced 1973 original components LS7 with only the towanada build date on the pad. The car carries original yenko badges (pot metal showing signs of pricking and age wear and fade) and 427 hood and tail logos that are consistent with the yenko badges (fading and pitting) the 427 badges are painted black inside the outline of the numbers and show consistent age wear. The car has lightweight hood springs that would be consistent with a glass hood and wont hold the steel cowl hood up. they appear to be galvanized frames as the paint is flaked off.When I provided all the information to Warren and he graciously recalled that Don had done possibly done 3-4 cars in cooperation wth Dana as an extended effort to try and get a foothold in California. He felt the effort was halted and Dana continued on their own. The car has its original small horse tach, was an automatic originally and converted to 4 speed years ago as the pedal wear is consistent with the 77k on the odometer and is void of an in dash fuel gauge as it had the console and cluster originally ( has been removed for the 4 speed conversion ). the big springs and heavy rear were my first puzzle. Rear is date coded to car and consistent with a big block (I believe it is original and has not been removed, no alterations to the original body with regards to panels etc.... and as far as I can tell 1 repaint done awhile back as the yenko tape is dry and brittle. The car is and codes as a Dayton Yellow / Black vinyl top -- heavy suspension and big disc brakes .. I am aware of the fact and warren verified that these California "legends" would not have been offered as the ditribution point for Yenko on the East coast was Norwood Ohio. The car was definately ordered and converted and I am trying to obtain as much info as possible. I would appreciate any response.
