sand blasting and powder coating

[77mk1]

just picked up some original stock mag wheels from 1975 for 60$ and was wondering if anybody in SA know of a good and cheap place to get them sand blasted and powder coated.

one other thing, does anybody have a interior light that will fit in a 77 gls or know if one from a convertible will fit a non convertible.

You went back to 1975 to get standard wheels? Can I borrow your time machine?
I doubt the Cabriolets have interior/roof lights... I might be wrong though?
There should be plenty on ebay.
