mounting buckets

Guys, my car was a bench seat car from the factory, but the previous owner had buckets in it when I bought it. All of thefloor pans will be replaced with new metel, so im going to have to re-mount the buckets (if I choose to use them). He just drilled 4 holes & slapped a bunch of washers on the bottom. Is this how its done? Did the bucket seat cars have a different floor pan than the bench seat cars? How did you guys that did the swap do it??

The four holes in a close group are from the awsome home made drive shaft loop that was on it!!
