Propshaft UJ's

I'm considering rebuilding my prop UJ's. There is a little play, so might be a good idea.
Looking at Rock Auto, there seems to be several versions/measurements.
My car is a 73 Charger, 318 with a light duty transmission (according to fender tag).
So which ones do i need to buy?? It looks like there are two or three different ones listed.

There are many, and usually 2 supplied on Mopars - 7260 and 7290.
The reality is you need to measure up what you have and order accordingly.

These are old cars and I doubt that you know its full history - there is also a "Combination UJ" so measure BOTH Spider arms, not just one.

Most likely 7260 but you need to check. Given the age of these cars you never know what might have happened in the past, I came across one that had some oddball prop on it that had external circlips and used a different sized UJ to anything listed for a Mopar.
