Hello, I'm brand new to this, or any forum. I have recently picked up a 1972 nova with a skyroof option, I think. I do not have the same measurements as what I was told most came with 36" x 36" . My roof cut out is 33" x 36" it has the wind visor and hardware seems correct. It is not in the best of shape and I need to replace. I've seen a few other skyroof owners can anyone tell me what measurement there roof is?
