Rare 1963 Riviera posi 3rd member. Disassembled and cleaned clutch packs, all steel clutches. Could use a set of bearings but not pitted either just old. I have the complete 3rd member assembly. I believe this works to '65 but don't quote me. Ring has a few slight pits. I was planning on using this in a '61 Lesabre but found it would not switch over even with the different '61 33 spline posi spider gears. Might also work in '63 '64 '65 full size Buicks too but no '61 or '62. Will install new bearing and races for the price of parts. Thanks for looking, Nick
Location: Tucson AZ? Is it apart or is it assembled? Looks like it is apart, that is why I'm asking. Thank you, Ted
It is currently disassembled but have all parts and will be assembled and torqued to specs before its shipped off. No parts were mixed up while disassembled. Located in Tucson. Nick
Reassembled today and ready to ship! Or pick up in Tucson. The picture of the lip has the "X" for posi but kind of hard to see.
Just for your own knowledge the posi rears all have that fill style plug that take a 3/4" open end wrench to remove. non posi has a 3/8" hole that you use a 3/8" extension into the hole to check the fluid level. Not saying someone could have installed a posi in the open style rear.
