Hemi Brake Booster

I am trying to repaint my Hemi booster, support bracket and master cylinder for my 1970 Roadrunner. My question is...Does the support bracket and attaching nuts get painted as an assembly? In other words, painted together or as a unit with paint on the threads and nuts and all?

I think everything was done as an assemble.

i just redid the booster/master cylinder on my hemicar and there was no evidence that the offset bracket/bellcrank had any black on the nuts. i believe the booster and m/c were together as one unit but thats it.
anyone else with answers to this?
all the best
frank.
