[Chevelle-list] 12 Bolt yoke

[Jim Sullivan]

All this U bolt/ Straps information makes me think about my situation.  My '69 Malibu 307 had a 3 speed on the floor with a 10 bolt open rear.  It has the U bolt.  

It's going back together as a 402 with a 4 speed and a 12 bolt posi.  Sounds like I'm not going to be able to use the original U bolts.  Is that right??  Even if I use U bolts, I'll have to get the bigger size???

  I guess I should have justified that statement with: In my experience. I have 1 68 and 2 69 Chevelle 10 bolt open rears all U-bolts. The ones that came on my 2 69 SS's are 12 bolt posi's both have straps and are original to the cars.

    Dale, I wasn't trying to mislead Ryan with a "blanket statement". In my experience, I had never come across a 12 bolt that had straps. And I have come across more than one or two. But I haven't worked on one with a TH400. Learn something new everyday.

      Beware of blanket statements; u-bolts were not standard across the board.  The 67 driveshaft, u-joint mounting method, and rear pinion yoke flange was different on the TH400 than anything else in 67.  The TH400 used the strap/bolt arrangement where everything else used the u-bolt/nut arrangement.  I've seen the strap/bolt in a 69 AIM as well.

      Ryan, U bolts were stock.

        Are most of you guys running a u bolt or strap style pinion yoke?  I guess I am not sure what 12 bolt Chevelles came with?  Mine didnt have one on it when I bought the housing and I guess I dont know.  I see a few on ebay that use the straps for the u joints.  Are all of them that way?  Chaulk this one up the rookie syndrome.  Again.

         

         

        Thank you

        Ryan
