78-80 uses a different master than 81- and up
That was for the change to the dual bore type needed for the new "low-drag" metric brake calipers. The parts are still interchangeable.

I can't see a reason it wouldn't work. But he says he wants a screw-on cap. I don't see the big deal about that. It is a little harder to R&R the big cap but it's not like it needs to be done very often since you don't need to remove the cap to check the fluid level.
I want the screw on cap for ease of maintenance and less mess. I check fluid every month before I go racing and the current reservoir is not see through. Plus I have to change the master so why not upgrade at the same time.

I think the ACDELCO 18M974 should do it for you. 1" bore with 1/2" and 9/16" fittings
Application is a RHD S10 pickup.

I’ll see if that is readily available at the part store so I can swap out under warranty

I doubt it since it's for a RHD. Should be able to get on Amazon with 2-day.

Would this be Overkill for a stock set-up?

Not trying to de-rail the OP. Just curious for informations sake?
