Camshaft78 said:I ad that same thought as well. Aftermarket t-roofs seem to have been pretty commonplace back then from what i've heard, but this is the first i've seen on a II.
What was common back in the day was aftermarket sun / moon roofs.
There may have been aftermarket T-Tops, or a factory supplied kit, and of course a refit from a donor car, but I'm unaware of seeing any.
