I have a '68 302 4 speed, the problem is I have the stock driveshaft with a 9 inch rear end, does anyone know what rear u-joint will work with this combo?

Is one end of the u-joint bigger than the other? If so you find a match from a truck u-joint. I have to find a u-joint this week also. The last time i need to find one like this I just went to the parts store and compare u-joints to what I needed until I found one. I think NAPA has a book with dimensions of the u-joints. It was 10 years ago when I did this the last time so I could be wrong.

I'm not positive, but I think there are only two possible universal joints, a 1310 and a 1330. The 1330 is the larger one and is what was used on the 9".

Measure it with a tape measure and go to NAPA, they should be able to fix you up.

I am not sure of the size but I would highly recommend Spicer brand by Dana.
