I have for sale a very little used SB Chevy gear drive setup from Summit Racing P/N G6700-Q. All the parts are there and everything looks to be in excellent shape.

Unfortunately, I don’t know if this is the noisy or the quiet version but I believe that it’s the quiet version. This set does not have the press fit Torrington bearing but the bronze thrust washer. Installation instructions are included. I would like to get $100.00 for everything plus the shipping.
