I think this is listed incorrectly I thought the Buick 8.2 new gear selection . was only the one run of 342 and 364 that was produced and then no more were made. 355 and 336 ratio, Plus the price is much t0o low for a Buick only part. What do the Rear end rebuilders say about this.

It is wrong... They will soon find out with returns. That is a 64- 67 gear set. these are 3.36 and 3.55 which are Pontiac and Buick 64-67 gear set for BUICK and 64-72 Pontiac 1964-1967 Olds shared the Buick and Pontiac 8.2 rears in those years. Jim JD Race
