72 Duster interior options?

I'm in the process of putting seats from a BMW 3-series in my 72 Dart. I got them from a convertible, so they have built-in shoulder belts, as well as full power adjustments. I set them back a little farther than the stock bench for added legroom. I built seat brackets from 2" square tubing and 1/4" base plates with 1/4" sandwich plates below the floor. They sit plenty low to the floor for generous headroom. I suck at remembering to take photos, but here are a couple.
