55/45 or 60/40 seats for bench
Read my earlier post on this:

The bench seat only has mounting studs on the outer edge. To install either bucket , 54/45 or 60/40 you need the inner mounting brackets, 4 ea. total. I just did this on my 85' Regal.
I bought a set of 55/45's from a boneyard out of a 93 Cutlass Supreme. I then bagged the inner mounting brackets from an 86' Regal Limited. The brackets are a bit_h to remove. Take a cordless drill with several bits up to about 3/8" & 2 batteries. You'll also need a pry bar, etc.
Drill out the spot welds on the mounting brackets and carefully pry them up. I brazed mine in because I don't have a welder. check them out here about 1/2 way down on the page:

You might also have to drill a new hole in the replacement tracks either front or rear side to get it to line up with the original outer brackets 2 bolts. No big deal, you only need to drill one on each side. Make sure that you test the lowest seat height location as it will rub on the hump. Also remember that the carpet adds 1/4" - 1/2" in needed height! I'm going to shim it up with 2" X 2" X 1/4" plates that I got @ Home Depot that already have a 1/2" hole in the middle. That way if the wife lowers the seat all the way and then moves the seat forward or rearward it won't drag on the new carpet.
I just posted 3 pics in my album, down at the bottom:
