I bought my SS SYE straight from JB, It was for a NP 241-C. On the web site they offer a 1330 CV yoke for 50 bucks more. The yoke needs to be machined but it is a 1330. My only complaint is the shipping, they ship UPS ground so you have extra fees when it gets here. If you order for JB have them overnight it on a plane, you will actually save some green.
On the drive shaft topic I found a shop in Salt lake City, Tattons, They quoted me $250 for the front shaft, $235 the rear and $60.00 shipping through the USPS. Both are CV shafts with heavy wall tube, I'll post pic's when they get here. I ordered them Thursday and Curtis was going to ship them today.
When I talked to DSI they rough quoted me $750
When I talked to Curtis they were busy building shafts for vendors going to MOAB to sell out of the back of their trucks.
