alright theres got to be someone here that knows something about these things. when i bought my car i thought it was a good great.... now i'm kind of kicking myself. it leaks, it's cracking, and i have no idea what that hell it is! does anyone know who made these things? i heard somewhere it was the same sunroof used on Jags of that era. it's a 72 nova by the way..... hmmmmmm any info would be greatly appreciated.
