How hard to add paint divider chrome to cab ?

[Green Machine]

I may want to add the divider chrome to my 70 and do two tone paint job. Cab did not come with that trim. I have the trim and clips from a donor and my other truck has the trim so I can get measurmennts and spacing, but how would you fasten the clips to the cab ? I thought of pop rivits but they seem to big and could make potential leak and rust spots. Is there a way to weld the little studs like original to the cab ? Any thoughts ?? Thanks
