I've read all the posts...and am still confused. I have a 65 GT, SJ-May, factory air, 7-blade fan. Car currently has a metal fan shroud, but looking at the MCA Judging Rules, its says my fan shroud should have a rubber piece stapled to the passenger side of the shroud. So, originals must have been plastic or some other material other than metal, correct? Is it even remotely possible that my car came with a metal fan shroud? NPD sells a plastic fan shroud with the rubber and staples, but notes that the rubber is not a thick as original. If proper thickness is absolutely required, does anyone else sell the proper part...or am I destined to search for an OEM part? Thank you in advance.
