Gearing a HO72?

[Lurch830]

I've got a set of 4.10 gears for my '72 C30 and with ECGS being ~30 minutes away I paid them a visit to talk lockers & re-gearing. They think they have a HO72 master install kit and I plan on picking up a 14bolt grizzly or lock-right locker after I grab some junkyard axle shafts. Since this will be a Frankenstein rear end (HO72 carrier & gear with 14 bolt locker & shafts) ECGS will not do the install because they would not warranty it (understandable).

I've watched people re-gear axles & install lockers, but it has never clicked in my head so I don't want to attempt it. Has anyone tackled this before? If not, any recommendations (bonus points for in/around Stanly County)?

Have to tag @Jody Treadway

Bring it up to South AVL and I'll knock it out.
@Chris_Keziah is probably closer and does somewhat decent gear work

@Jody Treadway & @Chris_Keziah , do either of you see a problem with this Frankenstein set-up? When I get all the parts together I'll reach back out...

 

[Jody Treadway]

Not at all.

@Lurch830 or @Jody Treadway one of you needs to document this build for those of us with a special place in their hearts for the Eaton axles.....also, @Lurch830 ...you should probably document a full disc brake upgrade at the same time, just because!

You will likely need to machine the "side gears" of the 14 bolt locker for clearance so it can unlock and possibly trim the 14b shaft down a little depending on year of eaton vs year of 14b shafts. Lots of info on Irate to digest on these axles.

I have several HO72s waiting on me to turn one into a kingpin front setup trying to have a matched fr/rr pair

I have some disc brake brackets you can have for that axle.

I don't see any issue from what I know about those. Shoot me a message when you get the parts together, my parents live in Stanfield so I frequent there every once in awhile.
