I just bought a moser 12 bolt and have replaced the stock u joint on my drive shaft with the recommended 447 part number. I am still having fitment issues. I have attached an image of the problem I am having. Anyone have the same fittment problems and what is the recomended u joint replacement to fit in between the tabs on this yoke. Also, how do I know what size my yoke is so I can tell the part store what I need.

Thanks in advance,
Brandon

you need a 1310/1350 conversion u joint assuming you have a stock driveshaft.

if you dont get any sponsor feedback you can call moser at 260-726-6689 and they will be able to sell you one of theirs or give you a cross reference number for your local parts store.

Napa 240-0447X is the conversion U Joint that you need. Bob

Thank you very much for the info. Unfortunatly the info about napa led me to the exact same part as I purchased before. A 447 u joint. Can someone please use the measurements I provided below to tell me if I actually have a 1350 yoke on my diff. I broke it down in every angle I could and even stated both metric and standard. This is the last thing I need to finish the swap so any updates on what yoke I have and what U joint I need would be very appreciated.

Thanks again in advance,
Brandon

hmm from what ive read a 1330 has a length of 3.625" and a cap diameter of 1.062" and a 1350 joint has a length of 3.625" and cap diameter of 1.188" assuming your measurements are accurate a 1310 is 1/4" too short and a 1330 is .15" too long. which i suppose isnt bad but a 1330 has a cap dia. of .013 too large. i dont know what tolerances can be allowed so i wont recommend anything. i'll see if i can find something on spicer's site.

come to think of it, when i installed my 1310/1350 u joint it was a little snug going in.

i would try a 1310/1330 u joint.
