Are they the snap rings from the CV joint side the ones you need?
If so I am going to be rebuilding my driveshaft with different joints and whatnot so if you like I can take all those snap rings off and mail them to you.
PM me your mailing address if you want them, I think I can just put the clips in an envelope and send them your way. They are from my stock TJ front shaft, should be about 50k miles on them.
If you want brand new, I don't know where you would find those.
Perhaps just buy some cheap u-joints from the parts store for the clips and have some spare u-joints.
Try calling Tom Woods as I bet he can help out, when I was running one of his shafts he sent me a ton of grease fittings for the shaft since I lost one of them on a trail
