WTB 1959 POWER Swivel Seat Base

I have a 59 DeSoto with manual swivel seats. I'd like to upgrade them to power, mainly to get a bit of upward travel in front and downward travel in back (in other words, tilt). I am looking to buy a complete, working power seat frame mechanism that I can just bolt my existing seats and armrest to.

Anybody got one for sale?
