‘67 Disc/Drum - upgrading rear axles to 5x4.5 - any replacement drums?

I am upgrading my rear axles to some Yukon 5x4.5 units & need some drums to go on. I didn’t know if there were some ‘74 drums I could possibly bolt on or if I should just swap on a disc set-up.
Have you looked into having your drums redrilled to the 5 x 4.5 pattern?
Anyone just swap some later 9” drums with the 4.5” BC.
