T Billegen,
The reason I ask is (yes ,it has to do with Jack Douglass)that all of the Douglass COPOs I have seen were ordered in this same configuration.

Jack calls it the 'Yenko Blueprint'.
He copied 'shippers' which were left in a couple of the first few Cannonsberg Yenkos delivered to his dealership.

He noted that he added Endura Bumper(a rare Yenko Option) and a few other options or option deletes. He remembers alot of GM hype and dealer promo info.about the Endura Bumpers.

He also copied Yenkos emblem placement. This has been consistent on all 4 Documented Douglass Yenkos thus far.

Jack says that at least one of the first Yenkos delivered (the one used as a blue print) had the Chevy Bowtie still on the tail pannel with the Yenko Badge installed to the right but in parallel with its two own holes and no 427 emblem present.

Does your Yenko have its original tail pannel and are there any "non traditional" holes in it?
