So these are the series 2 GTV floor panels (the difference being in the seat mount point areas) and came from Alfaholics. I'd say they look like they came from the same supplier (although I can't be certain for sure) but they are of identical workmanship quality as the ClassicAlfa ones. To be more correct for the year, they really should be used on the 71 and later GTV's. Notice that these don't have the reinforcing for the seat mount points (I'm guessing that the suppliers are only getting around to adding these in now).
As for the front floor panels, the one on the left is an Alfaholic supplied one and the right is the ClassicAlfa one. Again both of identical quality and are dead ringers to the original floor panels on th 69 GTV. I will finally get to work on this area of the car.....not sure when but soon.
