Is the Napa 447 u joint greasable? The Neapco 1-1153 is and I would rather have a non serviceable one. Actually your original u joints are not 1310s they are saginaw 44 or s44 or 3R. So you need a 1350 to S44 or R3 conversion u joint, witch is either the NAPA 240-0447 (PUJ 447) Precision 447 or the Neapco 2-1153.

I bought a Precision U-joint #447, but I haven't installed it yet. I just put my 9" in the car yesterday and that is all I lack is the driveshaft. Stock is 1330 and the 9" yoke is 1350.

I havent put my driveshaft in yet but I took a micrometer and put on it and the NAPA 447 and the spicer one i have in it are both the same size in roundness and in width. Im using a spicer SPR-539 after the factory one failed. Whats the difference between the two? I have the NAPA 447 but dont want to waste time putting it in if I dont need it.
