I would love to see the pictures. I may even know the car.

Pics for sure.

Only approx 355 of the W27 rear ends were factory installed on any of the 1970 W-Machines. I had always thought this option was only available on W-Machines, W30, W31 and W32?

How many total aluminum W27 rear ends do you think were built?

I have also seem them on two of the 1970 442 pace cars which were not W30 cars.

Just looked up the option list offering for 1970 and it shows availability of the W27 on F85,Cutlass S with W31 or W45 (rallye) and on the 442 with W30 required. I will assume that the Pace car W27 I saw were not original.

Very cool!

I just saw an ad on FB Marketplace for a W27 rear in PA for $28K. I guess there aren't too many around and his ad says no codes are stamped in it.
