sorry i had 1 of my part numbers mixed up. that is the small mopar u joint, If i had to guess compared to your old ones the grooves are slightly off,but the joint end of cap to end of cap is the same length I run across this all the time, try to find a spicer joint as they are almost always right, if someone in your area specilises in building driveshafts try him for a joint. these guys normally

as you know the 246 and the 315g do not interchange. assuming you have the right u joint, if there is no grease zerk they are packed with a lot of grease, compressing in a vice might force enough grease out to get the clips in, but first, move the joint from 1 cap to the other, if it seems to go deeper into one than you laid a roller bearing down in the cap, just thick enough to give you problems
