Half Shaft Universal Joints

Are the two universal joints on the half shafts the same part used on the drive shaft?

Thanks

nope - the 1/2 shafts are all the same but those driveshaft joints are a different size. Perhaps someone will chime in with some part numbers for you.

The Spicers are OEM, but are discontinued.

The halfshafts endure a bit more load, and therefore their u-joints are a good bit larger than the driveshaft u-joints.

FYI,
The driveshaft doesn't move so the u-joints don't wear much.
I pulled the driveshaft out of my automatic 87 at 190,000 miles; if I didn't already have the u-joints and it wasn't such a pain to get out I would not have changed them.
I would think a manual car would be harder on u-joints.
I decided to change them when I changed the halfshaft u-joints for the 2nd time.

the drive shaft uses two spicer 1310 series u joints. The half shafts use spicer 1350 series joints. Those are series numbers, not part numbers. The 1350s are bigger in every dimension, than the 1310s.

Race on!!!

Spend the extra $$$ and buy the solid 1350's for the halfshafts
The 5-799X is the same as the 5-800X listed above but without the coating for use with aluminum driveshafts.

As I recall, Action has a good price but S/H will make the difference in the end. Try to find them locally first. I would also look at rockautoparts.com. Reasonable prices and shipping.
