JBugs has separate part numbers for:
1946 to 1970 “standard” Beetle floor pans.
1971 and 1972
1973 to 1977
The year-specific pages imply the only difference is the seat rails.

That “center hump” on the 1973 to 1977 bothers me. It appears to be just more stuff to cut off the pans.
I believe any year will work. Especially since even Standard and Super Beetles share floor pans.
