Re: COPO 9511
Yenko used a COPO 9513 for the Stinger Corvair project 3:89 positraction differential
some info may be found by researching the speedo cable adaptors that were needed for the 4:10 rear. I am not sure if they were needed for 4:56 or 4:88 or if they had anything to do with the RPO G84 that was added to the window sticker for 4:10 gear. It was only $2.15. Looking at 1969 window stickers a 3:73 gear car only has RPO G80 but a 4:10 gear car has RPO G80 and RPO G84 Maybe the COPO 9511 needed a special speedo cable adaptor?
