I took the cover off an unknown 10 bolt this afternoon. It was beautiful inside, but the only mark on the ring gear was
GM 36; there was no ratio.

There are marks on the outside of the pumpkin that say
J-08. Without counting teeth, can anyone help me determine ratio? Been told it's from a 75 ish Lemans, and it was set up for coilovers. Thanks

Your lack of preparation is not my emergency
