Hey Kevin, thanks for taking the time to respond and pass along the info.
As per the wipers, did the roof have the openings/ports (lack of proper term I am sure) on pre-77 and after too? To me it looks as though the roof had original wipers mounted - View attachment 3643564
Ok, I might be wrong. Yes I am.
My LC is a FJ45 and has an all metal roof, so that might account for the difference. See pic below.
As you can see on my roof the two holes you have are for bolts to the windshield frame.
I remember now that the semi-circular cut out is for the washer nozzle, not the wiper motor.
The frame is from a different year that had the nozzle in the hood, so that is where I put the nozzle.
