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 carry top of the line parts, but its going to cost.
