Omni/Daytona buckets in Duster?

Anyone mount front buckets from a Dodge Omni/Daytona (late 80s)in an a body?
Saw this on a site once, and they looked like good cheap option. Just got a lead on set for $50- very nice set, wanted to see how much work it would be to mount in 72 Duster with stock bench.

Any help??
