Bucket seat compatibility

Those are '70-71 Duster/Demon seats (not sure if they'll fit your 73).

Foam/covers get pretty specific. Here's a link for foam just to give you an idea:

Covers are going to be $300-$350+ (more if you pay an interior guy to install), but at least the foam/covers are easy to find from multiple places. If you can, track down the actual manufacturer bc usually these vendors are selling the same part with big markups and price differences between them. Shop like a girl before you buy- saves money lol.

This is the correct seat for your car (73-74):

My 72 Demon had '73 buckets in it when I bought it. If you're wanting to go correct for your year beware!! I couldn't find foam anywhere. I looked for a month lol before I gave up. I got really lucky and found a pair of 72 buckets at the Daytona Turkey Run show last year. Seats get expensive so quickly. It would be worth your while to check them over carefully- are the tracks all there and working...is the foam good...sensor intact...backs ok...frame good, etc. All of those parts are $$$$. It could be cheaper to sell those to someone needing 70 seats and buy ones that are close to good or perfect- a chance to go correct if you want. My 72 buckets just need covers and I'll still be into them $1K by the time they get bolted into the floor- seats: $350 covers: +-$450 (with rear bench) install: +-$200 (buckets only...if I bring the seats separately..and if I smile real pretty). I sold my 73 seats pretty quickly on ebay to a guy with a 73 Duster. If you just want good seats and aren't a purist, look into aftermarket or seats from other cars. A U-pull yard will have plenty to choose from. Check this link out, it's pretty great:

I hope this helps and good luck :) Congrats on your Duster, you'll have a blast with it.
