A little help please - which should install first?

[68dartgtman]

I have finished the painting on my doors - completely strip of all hardware. Now it's time to put the doors back together - which should I do first -
install the belt moldings or install the vent assembly & door glass?
I don't want to have to do things twice - is it possible to fit the belt moldings on after the vent assembly & door glass go in?

thanks Guys !
