Also, the other side looks like someone took a hammer to it and broke it: Pic of Yoke I've searched my normal replacement part sites but was unable to locate a brand new yoke. Any suggestions for me?

You might try a shop that specializes in rebuilding driveshafts, as they will have sources the average parts store won't know about. It's also possible that one might be listed on Ebay, but be absolutely sure the diameter, length, spline count, etc. is correct before ordering one from somewhere before doing a side-by-side comparison. Fortunately, there's a pretty good bit of interchangeability on slip yokes, sometimes even crossing over car lines- - - -GM, Ford, MOPAR, etc.

They should be able to get you a yoke. | | | | | Joined: Jul 2007 Posts: 444 Shop Shark | | Shop Shark Joined: Jul 2007 Posts: 444 | I agree that you need a new yoke.
Any chance that you can supply a GM
part # of the yoke you need ?
I'll see if I can hunt one down GM NOS.
Of course you can always do the
scrap yard thing.

Lots of time people have something listed by p/n and have no clue as to what it fits. I have found a lot of hard to find parts like that. | | | | | Joined: Jul 2011 Posts: 28 New Guy | | New Guy Joined: Jul 2011 Posts: 28 | I agree that you need a new yoke.

New Jersey I assume it will be on the yoke itself? I'll take a look tomorrow.

The best would be to find the part number. I have all GMC and don't know much about Chev. It will probably be the same as a GMC and Chev and GMC use the same part numbers. However, GMC and Chev have different group numbers. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | master parts manual here, near the bottom > "55-57 1/2T (except hvy dty & 4 spd)", 1&5/16 dia bore, should be the same as 59, p/n 3707059 Bill | | | | | Joined: Feb 2004 Posts: 29,771 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,771 | There are dozens of brand new yokes on Ebay right now- - - -just need to figure out which one will fit!
