I have a concourse 1970 442 W30 rear end TO code 3:90 gear for sale. Everything on this has been replaced with new parts (have original drums on car). Julian date is 345. Rear end was sand blasted and professionally painted. I can sent pics to you cell phone if interested.

I would trade for a 1970 hard top coupe passenger side GM NOS quarter panel.

I also have a W27 cover on the rear end and new fluid. Price is $2300. I'm in the Archway Olds club
