Guest BJM Posted January 11, 2012 Share Posted January 11, 2012 Mine is sold. Hard to find and not sure about inter-changeability between the Riviera 3.08 and 3.42 posis and those for full size Buicks. They are out tere. There are 1-2 on V8Buick.com now. Be prepared to pay. One is $500.00 and most are $350 to $1000. Link to comment Share on other sites More sharing options...

They apear to be the "Tin hat " type diffI don't think so. Ted Nagel and some others are experts on the posis. Also, get a sign on to V8Buick.com and go to the gears section. There is a guy there signed on as MONZAZ that is an expert. The 10 Bolts I think are for the Skylarks. Link to comment Share on other sites More sharing options...
RivNut Posted January 23, 2012 Share Posted January 23, 2012 MONZAZ has one for a '66 for sale on TeamBuicks.net. Says it's for a '66 only because of "equal size carrier bearings?" No ring and pinion, and he doesn't specify any series. Can you find a '66 rear end for your '65?Ed Link to comment Share on other sites More sharing options...
Ted "Wildcat65" Nagel Posted January 25, 2012 Share Posted January 25, 2012 Hi, just saw my name mentioned . How soon are you going to need the 3.42:1 posi?I may let one go but there are complications, as They have to come out of a car! I work slow too.
