No..70-71 models had the rectangle shaped and 72-74 had the 4 round in the rear...someone has altered it if it has the rectangle style. The rear panel is an easy alteration to do.
Thanx I thought so my mate was looking at it in America at the moment, I just wanted to check because in Australia we has a lot of mixed and matched stuff come out from our car manufactors in the 60 and 70s
