Floorpan

I'm doing pans in my '65 Valiant now. I got super lucky and bought a used left side pan from a member here. I bought the ABS pans for the right side. They look like they will fit pretty good.

I put AMD half pans in a buddies '69 valiant recently. That car is still in my garage and looking at the two cars side by side I'd have to say making the later pan work in a '66 and down car would be a ton of work. The tunnel is a lot smaller in the early cars and the seat mounting tabs are spaced differently. The floor is shaped a lot differently at the seat mounts as well. I'm sure it can be done. It's just going to be some work. The larger tunnel might be nice for bell housing clearance but I'm thinking you will see some fitment issues at the torsion bar cross member.

If you decide to make the later full pan work let us know how it goes. I was considering doing just that with mine until I found the left side I mentioned above.
