Garry K 'Bolter G Joined: Mar 2004 Posts: 83 Port Ochard WA	Hey all, I got a 12 bolt truck rear, and it is complete and in good shape, EXCEPT it is missing the 2 spider gears... Everything else is there, just not the two spiders that ride on the center pin. Any body seen this before?? Came out of a full time 4x4. Anybody have a dead rear with a spare pair of spiders??? Thanks in advance, Garry K Garry K in Pac Nor West 1948 Chevy PU 235 SM420 4 spd 1932 **** B pu 1964 Datsun 4x4 with SBC, SM465 4spd and Rockwell xfer Dana 44Fr and 12 Bolt Rr.
