I have searched and am not finding solid info on this. I did a 14ff conversion and need the corect ujoints to piece together. I have spent the day visiting local part stores and trying to cross reference #rs. I also went through their inventory at two places and the larger cap 14b joint will not fit on the smaller 10 bolt joint arms. The conversion page says 1310 and 1350 joints. I could only get one # converted and pulled. searching the data base is not coming up with more info. Help!!!!!
