    alec296 i need another buick

    a 12 bolt and an 8.5 are two different rear ends
    but a replacement should be hard for either to get
    8.5 rears are basiclly still used and 12 bolt can be had from summit as well as moser
    confirm rear end type

    Post some pictures and will ID the thing. need a yoke area shot and rear cover shot. how many spline yoke is it?

    Question? How did you brake the yoke removing it??? :error:

    If you call 216 464 2313 x240 maybe discussing the problem we can get you what you need. I have plenty of parts here and sure we can get something to work or the right part dead on. Jim

    Hi, My Mechanic Is Working On Car In Washington. We Are In Arizona For The Winter. We Are Restoring A 72 Gs To A 455 Stage 1 With A 10 Bolt Rearend. I Have 71 Parts Car That Had A 12 Bolt And I Ordered A Disk Brake Conversion For It Before I Had It Apart. Then Put In New Bearings And Seals. Went Looking For A Posi And Found All Kinds Of Things That These 273 Gears Do Not Convert To A Posi Without A Total Change Internally. When I Took It Apart We Hammered On The Yoke And Have A Small Chip On The Corner. We Will Keep Your Number And Will Call When Have Your Questions Resolved. Thanks For Response. Tom Lundbom,
