Yenco may have messed with atruck or two... but sure isn't likely.
He hardly did anything but apply stickers... he had the factory build all the awsome cars under the COPO program. The COPO was a back door way to build odd ball cars and trucks that were not normally optioned the way they were needed for fleets such as cop cars, taxi cabs, or fleet trucks. Odd ball paint colors, or a loaded cop car with a vinal rear seat and radio delete. Some of the dealers (like Yenko and Nickey in Chicago) would COPO order stripped down muscle cars with mege motors and HD driveline parts, and then install there stickers ans such. COPO would require the dealer to order so many, and some combos were actually turned down. Most dealers had no idea about this back door oportunity for the ultimate hot rods, and if they woulda know, they most likely wanted nothing to do with it.
There are a hand full of COPO trucks out there, and some on this board, but they were all done up in odd ball fleet order, and not 427 alluminum big block type orders. There is a 427 truck in a musium, and it is claimed to be a COPO... but honestly I highly doubt it since there haven't been any storys come to surface about others like it..and since COPO always said you need to order X amount done up this way...there WOULD be others out there. There is a chance, but untill I see an original SPID label or build sheet, I say it is bogus.
here is another pic...probably from the same day those two black and white pics were taken.



oops... my yenco pic is the same.. I was confusing it with the indy pic...the one with the orange and white trucks. Oh well.
Here is another neat dealer pic too.
