COPO 9511

[Schonyenko2]

I have a copy of the ad for Kevin Suydamn's 69 Yenko Nova. It shows 4.10 rear. Does not state BE, or BV. Marlin, you explained the other day that the people who restored the car thought it was a COPO until they figured out that the info was not lined up correctly on the sheet. Any insight from that sheet to add to this discussion? It was my understanding that the 69 Yenko Novas were BV. If they started life as L78s are there docs on how they were ordered with rear codes?

I'd like to see docs on anything higher than 3.55. I've had an e mail stating 3.55 was all you could get in 69 without going through the 9511 process.

Hello Ken,

The original order form would have the non-standard axle ration written in on the Special Ratio line and the ZQ6 Performance Ratio box checked. Of course it would have to meet the rules in the Vehicle Price Schedule.

The non-standard axle ratio would be listed on the Window Sticker. Either under the order code listed above or possibly as ZQ6.

Axle code would not be listed on the Fisher Body sheet. However, the Engine code could be for L48, L34, and L78 in 1969. I believe that was the part that started the COPO thought (by it being on the wrong line due to a printer misalignment).

Another document that would show the axle code would be the GM Chassis Broadcast sheet. Line 6 Box 236. I have only ever seen one for 1969. While I have seen about a dozen for 1970.

And finally the POP would show the broadcast code.

Greg.
