eaton hub info

[70 beast]

just recently i had to change the outer wheel bearing on m ho52 axle. i got the bearing, preceded to install it and decided to change over to a later year hub off an Eaton in order to widen it(if it works).

i havent got them yet and need answers to a few questions before i do.

1. will a set o hubs off a latter model Chevy will fit mine. i believe mine is off a mid 60's pick up? i also think its got a 63" wms. (need it to be at least 65").

2. does it matter if i get it off a dully or srw truck.(dullies seem to be more available where i live)

will the later model hubs bolt up?

any help is greatly appreciaed. thanks
