After going through some serious garbage with local parts places (that are usually really good and have or are able to get all the parts I want) I decided to post some info here.
If you are going to try and get a new ball centering kit (cv centering yoke) for the front DS of a 97 Wrangler, a lot of places will either tell you it doesn't exist, or that they can only get you the ball kit to rebuild. None of which does any good if you actually want to replace the ball socket as well.
After going around with even the Jeep dealerships (two of which told me the front driveshaft wasn't a 3 joint ds... go figure) I found these cross reference numbers etc. for the exact part.
They are as follows:
Spicer part #211355X "Spicer C/V Socket Yoke for 1310 series Ujoints"
If they can not cross reference that, the dimensions for it are as follows:
Dimensions between the locating tab on the centering yoke is 3.219 inches (3 7/32 inches)
and it is designed to fit 1 1/16" ujoint cap.
If parts people can not find it with this information, then there is a problem
Just trying to save everyone a bit of hassle that I went through again today.
