Hi all,

Super stoked here, as I believe I've found some 4.10s for my 3600. I just wanted to confirm that both of the '68-'72 HO52s and HO72s are compatible with my stock axle? I've found a guy with one marked RAJ G308 and I believe it's this one from previous posts.

The �72 series C-20 RAH, RAJ, RJA, RJB, RKK, RKL, RKS, RKT, RJP, RJS, RKB, RKC, was an Eaton HO-52

I'm just confused about the difference between the 52/72 models and really hope that I've found 'The Holy Grail' wink

Thanks!
