   Wanted to upgrade to Posi with 3.55 gears. I have no clue on this one, so I'm open to suggestions. I would like to stick with my stock 10-bolt BOP. Thanks

   Auburn and Yukon make new posi’s units for the BOP carriers! New gears 3:36 and up are also made by a few different vendors!

   Parts are no problem with the 64-67 BOP rear. I believe this is the Posi,

   And gears,

   but check with Monzaz or Brian Trick to be sure.
