The biggest thing that NEEDS to be done(won't work without this) is to thave
the center hole enlarged. The datsun center hole is about .080" smaller than
the triumph center, the drum will not fit unless this is done. The retaining
screw aren't a big deal and you don't need to worry about IMHO. I don't use
them and I don't have a problem. You do not need to do anything to the stud
holes, they are fine as they are. If you do decide to paint, flat black is
the only option for heat transfer, but I do not have mine painted. Also
since I assume these are breaker yard drums, have them check for runout, you
don't want pulsating drums.
hope that helps
