We have 3 1966 C10 cabs in my local salvage yard here in Columbia, SC. I don't know that the floors are any better than yours, but a complete cab from my salvage yard is only $300 with doors and $170 without doors.(Minus seats and steering column too I guess, but that might be included too if you're lucky.)
