this looks like a blue 4sp cutlass that sold on ebay back in 2012

Tom, I am going to respectfully disagree on what it takes to change the firewall from non a/c to a/c on a GM "A" body in this case. The only panels needing removed are the inner wheel house on the passengers side and of course being able to cut and weld the firewall.

There is no "proof" at this point that this is not a real W-31 but someone would have needed to go to great lenghts to add factory correct A/C throughout. Think of adding A/C to a 1969 Z28. Sure it can be done, buy why go through the effort and the reason the factory didn't do it to begin with is that the "big" cam caused lack of vacuum.

However, I did not see any proof presented that this is indeed an authentic W-31?

The brake master clyinder and booster apprear to be reproductions based on the pics presented, but as mentioned power/vacuum opperated disk brakes would not be factory correct.

The radiator top plate is correct for a 3.91 geared car which would not be correct even in a standard Cutlass 4 speed with A/C although that is a bolt on item as well.

Oldsmobile POP's are generally a plastic card and do not verify options or W-31 status.
