I am looking to replace the missing floor in my old drag car 63 roadster,with an original floor.
Were there any variations in model years?
It would just be the section between the firewall to just behind the seats and from from rocker to rocker,as the rear back half has been narrowed.
Thanks

Some (maybe all - not sure) 63's had a dropped area under the seats I believe. I want to say the first cars had it and it was transitioned out during the model year - again I'm unsure but the 63 guys will know. Seat mounting to the floor was revised over the years but that relates mostly to riveted on reinforcements.

 

As far as fit they will all fit 63-67 if you don't care about being original. Early 63 was by itself with tool boxes under seats. Late 63 to 66 are the same 67 was also by itself, with e brake and seat mounting changes. But all will fit a 63. I have installed a floor in a 63 cp a few years ago. not an easy job to do it correct.
