I just figured I would post an update. It was easier than I thought. Zcardepot sells Yokes for a couple different flanges. In my case it was the flange that measures with OE U-joints (Which I have to replace anyways) Measuring 1.9 X2.25 Inches with 10mm bolts holes. The state specifically to adapt the driveshaft to an R200 Diff. Thanks for all your help guys. I will post a link in case anyone else finds this useful.
