Still, there were Dodge St. Regis police packages. I saw one at Mopar Nats in the 1990s, had the 360HO dual-cat full dual exhausts under it. I looked under the driver's seat and discovered the reason for "No Power Seat" for the 1979 Cordoba 300s, NO ROOM, width-wise, to fit the power seat mechanism. Only about 3" between the seat risers. The normal lh bucket seat used 1/4" steel straps (maybe aluminum) to allow the wider apart seat base studs to adapt to the narrower floorpan in that area. Had to have room for the cat converter on the lh side.
That particular car had a 440 in it, which is dreadfully easy to do, with a 400 Cordoba subframe. The guy who owned it said it was a Fire Chief's car, so it was in very good condition compared to a normal police unit. All he had to do was get a new a/c line from the RV2 compressor to the condenser made.
Just some thoughts and observations,
