Left hand thread wheel stud
(What looks like rust in the knurl is copper colored metal)
All 3 have good knurls
1 is in great shape
1 is on good shape
1 had a bit more rust on the threads
All 3 i wire wheeled the thread section and was able to spin on a lug nut.
Compared to my 8 3/4 A body axles i am 99.9% sure these are rear studs.
Disclaimer.... I bought these used. I have no idea what type of life they had. They are yours free just pay shipping.
Pm me for the shipping details etc.
