I have a couple of u-joints that need replacing. The problem is my car, 69 Chevelle, is not stock and need help with a new set of u- joints.
The dimensions are, outside to outside = 3 1/4", diameter of caps is 1 1/16".
Transmission side used two inner clips on the yoke end and two outer clips on driveshaft end. I have a ST-10 transmission.
Rear u-joint has outer clips. They are around 40 years old by the way.
Edit: if squeeze the caps together outside to outside is 3 7/32".

Thanks SFD, the chart measures right when I use the Outside lock chart but when I measure the grooves like they say to for the inside lock joints, nothing matches up.
Outside of grooves measurement is 2 3/8", inside of grooves measurement is 2 3/16". The inside lock cap measurements are also different.
I need a 1310 with grooves in the right spot.
They kind of resemble Lakewood u-joints, I hope not, Lakewood u-joints are $90 each Canadian.

With the caps removed, do both sides of the cross measure the same?

My conclusion.
I need 1- Moog 225 u-joint for the transmission side.
I need 1- Moog 280 ( 1310 ) for the rear diff side.
Or Neapco- 1-0350 for trans side
Neapco- 1-0153 for rear diff side.
Thanks you guys for the charts and info, it did help.

Thanks shovelrick, I think I found what I need, just have to get them and see.
I am leaning towards the Moog over the Neapco. Moog is USA made not sure about the Neapco ones.

Spicer has been around for a while
Spicer would be a good brand, not sure if they have the size I need. I could not find a descent chart with the dimensions listed, I might try again, no rush. Then I have to find some place in Canada that sells them.

Go to any Napa store. Have them grab their catalog for u-joints. They can measure the old one and in the combination u-joint section they will come up with it.

Thanks MrGardman, I did that with my local parts store, they can get the Neapco ones. I will probably get the Moog ones, made in USA, I can get them online here in Canada with free shipping. Had no luck with the Spicer brand here in Canada either.
