WTB Posi unit and r&p (3.70-3.90 range) for a GM 9.3 10bolt cover. Mail me at camaroz28@tiscali.it Thanks Luca
Greetings: If you are looking for a ring and pinion for your 70 skylark and it has a 10 bolt cover you are likely looking for the 68-70 8.2 inch Buick gears. There are 9 3/8 inch Buick gears but they are found in big Buicks of that era like Rivieras.
You're probably not going to find anything with more than a 3.42 gearing, unless you find a SUPER rare 3.91 rear from a big car....
rearend hi have complete rear out of 67 rivera posi not sure of gears can pull cover if interested hank 1 440 563 4766
