Crewcab Rear Door Trim Suggestions

[RADustin]

Gents,

I'm going to purchase the Mar-K horizontal upper and lower trim for my '76 GMC crewcab.

They don't sell the 4 pieces for the rear doors(2x each door) so basically my options are-

-NOS, not sure where to source.
-Good repop, but which ones are good and will match the Mar K?
-Modify Mar-K front pieces to be shorter

Also I need fender lip mouldings. Are some out there better than others?

any other ideas/suggestions?

thanks
