There are fiberglass windshield frame options too. I almost got one but they don't work with soft top 73/74 (no channel), just the FRP models.
I'm wondering the difference of connection with the Land Cruiser FRP vs. the Columbian FRP made tops at the windscreen?
It seems like it would be a factory soft top windshield frame but who actually knows for sure until you pop that FRP up and see.

Again just asking questions, but I would have thought a factory soft top would have had the hood bumpers that hold the windshield screen, but all of the Columbian FRP ones I have seen don't have that. Neither do they have 1/2 doors, although I don't think thats any indication as well. Your VIN is for sure a soft top model, but I really wonder if when Toyota sent them to Columbia, were they spec'd with a standard FRP frame because they knew they were putting a Columbia top on them from FIVRES?
They look extremely close, almost identical to the same Toyota FRP tops so that alone would make me question if it's really a soft top windshield frame.
Differences I see
rear upper door latch is the soft top style, not the FRP with the latching mechanism like the Toyota FRP.
Windows are different attachment and single sliders with rubber gaskets, not the "RV" style the FRP uses
Gaskets on the B-pillar aren't on any FRP tops from Toyota.
No headliner, although that could have been removed.
It doesn't appear the top bolts through the main roll bar, no access holes on the trim (unless you take it all down) and the top fits differently around that hoop.
I would definitely just pop the front of that top up a little to get a look at the frame to make sure you order the right one. Just a few bolts and not much time.
