I have a ring and pinion set that I want to put on ebay. It has 27 splines, and the ratio calculates to 3.15:1. 13 on the pinion and 41 on the ring (10 bolt). Has a few markings for identification, but I dont know what they mean. Im hoping I can get some input on this set, so that my ebay posting is correct. I believe this is for a buick 8.2.
Link to the ebay post, if any of you are interested. Thank you for the help. https://m.ebay.com/itm/Buick-8-2-ring-and-pinion-set-/222984907400
