Bench to bucket conversion, need help please

So I took the plunge and bought buckets, summit brand with rails, The mounting holes center to center is 11 in where the car is at 12 center to center. my other question is, what did you guys do for the floor pan? Since it was set up for a bench and the pan is raised on one side near the door and the other by the tunnel is flat.


I looked on mopar resto parts suppliers sites looking for possibly a factory rail and bracket that will work with my current seats.

I was thinking of using aluminum channel for the one side the is flat in the pan?
open to suggestions or if you have any pics of the summit seats mounted in the car so i can see the brackets. I found a couple threads and saw what the factory ones look like so that helped a little
