Basically all older fords, Jeep wagoneers, Chevy 10 bolts. Just make sure you make sure the measurements are close and the spline counts match. I used to play that game. I went to the junk yard almost every weekend looking for spare shafts. Pretty soon I realized that buying spare junk shafts was eventually going to cost as much as warrantied shafts. If you can't afford full chromoly at least try to get some yukons from Randy's. They have some that are not chromoly but still stronger than stock and with a warranty. Keep checking the pull a part in Nashville. We used to go down there all the time when I lived in TN.
