just be sure you get the non-greasable 3R u joint . for my money I'd go with the Spicer maintenance free ones.

Advance auto also has what is called Brute Force Universal Joint, and they too are non-greaseable

What I really need is a 3r to 1350 conversion joint. I am putting a 9 inch in the car and the pinion yoke is 1350 does anyone know of a solid conversion joint all I find is greaseable ones.

Here's your GM 3R series to 1350 combination U joint. It appears to be greasable though……not sure if you can find one without the grease firing or not, but your best (strongest) choice would be without the grease nipple.

So the reason you want the non-greasable is because of strength?
