Which seats fit a 73 Swinger?

[sl7732]

Seeing as the price for original bucket seats are so high, I was wondering if anyone has performed any research on modern seats that will fit a 73 Swinger?
The local wrecker yards are full of later cars with good interiors but I thought it worth asking before I spend lots of time measuring differant seats to see what would fit. I can fabricate seat mounts etc and thought it would make for a much more comfortable ride with something more modern, possibly with electic adjustment.
If it makes any differance, the car currently has a stock bench seat.

Thanks.

Alternate bucket seats are a lot like chairs in a room. They are all about the same size. If you dont mind the extra bolt holes in the floor.
