Looking for full right rear quarter for Cutlass or 442. Must be rust free. 8106505107 Dave B. I found one with the NOS GM # 4032-600-70 R is this the right number?

 

The original part numbers are as follows;

sports coupe, 9870136-7
H.T. Coupe, 9870134-5
Cutlass Supreme, 9898788-9
Convertible, 8769148-9

these are left and right numbers for 70-72 Cutlass and F-85 rear quarters.
Enjoy, Paul

 

You can find singles of the NOS left side but it is very unlikely you will ever find an NOS right side by itself. The right side is always sold as a set with the left.

 

If Berejik Olds was still around, they would have it. If I was a millionaire, I would have bought all parts inventory of all Olds and GM dealers that were closing, along with the warehouse in Westwood MA

 

They had more lefts than rights also. I do not believe they would have sold a single right side but I could be wrong.
