HUGE props to 46Canopy for hooking me up with a source for these windlace retainer strips. Can't thank you enough, Dan

For those that may come later in search of info, after double checking my cab, there is NO metal retainer strip along the bottom of the cab doorway except the metal transition piece from the flat floor to the rocker of the cab. It is held in by clutch head screws and that piece in turn holds the weather strip that runs across the bootom of the doorway. There is a short approx 3/4" wide flat strip that holds the windlace on the "front" of the doorway - the part where the kick panel goes. And there is another similar flat strip that goes along the latch side of the doorway. Then there is a somewhat similar piece that goes over the top of the door way that interfaces with the long vertical piece I just spoke of and finally there is a more involved part that covers each A pillar adjacent to the windshield. Hope this helps. As soon as I get everyithng straightened and primered I'll post pictures to this thread. Thanks again to everyone that helped, Dan
