Problem is for gaskets, finding OEM ones are next to impossible. They may be out there, but tougher to find. Probably can find repros, but not sure how good they are.Thank you for including p/n's for these gaskets for other cars. I saw that someone else would like to know p/n's for BOP's also. I have a Caballero that I am upgrading with options not originally installed, and power mirrors are on the list.
For Regal/Cutlass, the sport mirror gaskets are the same for either side. P/N 20215096.
