I'm just going to say this, unless you are shooting for a show room stock truck that may be a real spendy transmission to have repaired compared to a turbo 350 or 400 or even a 700R4. Plus the old timers who really know how to work on them are getting few and far between.

The Dual range hydromatic rebuild kit runs 650 on Amazon https://www.amazon.com/Range-Hydra-M.../dp/B01HS86HXK and I'd expect having a shop rebuild it would take around a thousand in labor plus the converter.
Those hydromatics worked pretty good when they were in good shape but were a fairly expensive option and were usually sold to people who used them for in town delivery rigs.

To me it has to be that you really want an original hydromatic and not a later model transmission like a lot of guys would use and are willing to pay the extra to have it repaired if it comes to that.
