I don't know how close they are but some Monte Carlos in the 75-76 era had swivel seats in them. My upholstery guy told me these seats are in high demand because hot rodders like them. Good luck on your search.
73-77 A-bodies all had a version of swivel seats but keep in mind 1975 Hurst/Olds seats had removable/reversible insert cushions. One side of the cushion matched the primary interior color with the reverse side a contrasting color. Cars with Compaticolor interiors matched the cushion to the carpet color.
