Spicer u-joint part number

[Tom B Hargrove]

Can anyone out there tell me the Spicer part number for the u-joints on my 95 six speed, both the half shafts and the drive shaft?

Found this on another forum but can't swear to the accuracy although the author seems to have done his homework, hope it helps.

C4 Corvette U-Joint Information​

The C4 u-joints are 1310 series for the driveshaft (2 required) and 1350 series
for the half-shafts (4 required).

Within the 1310 and 1350 series there are u-joints intended for use with steel
yokes and others intended for use with aluminum yokes. The Corvette requires
u-joints intended for aluminum yokes. These are specially coated to help prevent
or delay galvanic corrosion which occurs between dissimilar metals like the steel
u-joint and the aluminum yokes.

The preferred Spicer u-joints are the

5-786X for aluminum driveshaft (1310 series)
5-800X for aluminum half shafts (1350 series)

However, these parts seem increasingly difficult to source. The numbers appear
listed as 'Unknown' on the Dana/Spicer website compared to other numbers that
display as either 'Active' or 'Discontinued'. I wrote to Dana/Spicer to ask about
the status of these parts but I have yet to receive a reply.

It appears that Spicer vendors are telling buyers to accept u-joints intended for
steel drive and half-shafts (apparently without explaining the differences
or possible consequences)

5-785X for steel driveshaft (1310 series)
5-799X for steel half shafts (1350 series)

As an alternative to Spicer u-joints, there are the following

There appears to be two versions of the coated driveshaft and
half-shaft u-joints. I have no information beyond part numbers.

Thanks, that's great information. I got the 5-799x number of this forum, but when I went to the Spicer dealer here, they told me that is was not what their book called for in my application. They did not show the half shaft number at all, and I don't have the number for the drive shaft in front of me.
I will go back with these numbers Monday and see if they can find them. Thanks for the reply.

Here are two more numbers that may (or may not help). My parts CD shows the following GM part numbers
halfshaft: 12522048
driveshaft: 14067678

I purchased one of the 14067678 numbers from the dealer once when I could not locate the Spicers locally, ended up not using it so it is new in the box. (BTW the GM part from the dealer does have Spicer forged into the joint. )
Sometime later I went to use it and discovered it is not the right size for the driveshaft OR the halfshaft. Not sure what the deal is there, could be an error on the parts CD or the part was boxed wrong.
My point is that if you end up buying one from the dealer take an old joint or the driveshaft with you to make sure you get the right part. I got stuck with the one I bought because so much time had elapsed before I attempted to use it, God only knows what it really fits.

That's a good idea. I told the spicer dealer that I would bring in one of my old ones to be sure the new one would fit. They have assured me that they can get what I need. We'll see.
Thanks for the input.

Probably because that is the HD 1350 uni without the grease zerk that people use for performance apps on account of being stronger. 1310 and 1350 are two of the most common uni's used.1350 used on C3 halfshafts as well as most pickups. Any dealer should have the cross reference book to same size in any brand. I can buy them off the shelf in Australia.

This should/might ID your "GOK" u-joint! There is more comprehensive information available but here is a link to a TCI chart for "most" OE domestic u-joints complete with all dimensions:
