Saw a big window TF today without deluxe trim ???

[TX58]

Went to Fort Worth today to pick up some doors for my 58. The truck I removed them from was a big window 55-56 but with no trim or holes for trim. Was this available back then? It's the first one I've seen like that. Speaking of deluxe trim, who knows how to install them? I was thinking today while driving 4 hrs to pick up my doors, has anyone found any plastic push in type clips that would work for installing the trim? Seems like it would be a lot easier and won't scratch the paint like the metal clips do.
