Here is a zone post with conflicting info on what year arm to get. http://www.m715zone.com/vb/showthread.php?t=18157

I dont know the thread pitch on either the drag link end that fits the FSJ pitman, or the drag ling end on the 715 knuckle. If they are both common thread pitch, like the GM 7/8-18, you can buy the 7/8-18 R-L inserts, and a piece of DOM tubing and have them TIG'd into a conversion drag link.

I am doing a variation of that with GM parts for my axle swap.

PartsMike has some good info and parts here:
