67-76 floor into a 65...
I put a later model in my 66 the front seat mounting and the tunnel in that area were bigger. (I sectioned it to fit) then discovered the floor well in the front was weaker than I had thought. the rear fit well and even the spot welds lined back up , the front seat (for buckets anyways was wrong on the later model floor pan so I cut it out to match the flat part of the 66 floor pan. the front section is about 1/2"- 3/4" wider per side depending on how you round the hump to the crossmember. the tighter it get to the original cross member the wider the pan is. you can see the holes cut out for the front bucket seats that I have to put in again. the rear section has different beading and the 2 large holes(closer to the back of the car) are in a different location than the original and I had to "trim the holes to make them round again. But the spot welds are in the same place ohhh seat belt holes on the side of the rocker are different too .
