71 K20, Eaton H052

Hi folks, My 71 K20 has an open Eaton H052 rear Dif. I would like to convert it to a locker, either manual or automatic. I called Eaton and they said unofficialy I could use a Detroit Locker number 225S10. I need 30 spline axles for the Detroit. Has anybody done this conversion and know of an axle that would work? The axle shaft diameter is 1.5 in. I don't have a length. Any and all suggestions are welcome. Thanks, Jack

personally..id just get a locking 14b and swap it out...not sure on the widths though..but if possible itll be much cheaper than trying to do anything with the ho52

been told and read the detroit form a 14ff will swap inside the open carrier in place of the spider gears . then the 14ff shafts the correct length will swap over also . then you have a eaton ho with a locker .
