Looking for real 1968 Super Stock Seats

The "real" SS seats you seek are not unique to the LO and BO cars. . Bostrom Seating still produce them albeit for construction equipment, off-highway equipment, industrial grounds keeping equipment, and some farm tractors. Seats Inc. make a copy of the same seat for the same applications. These things are everywhere and cheap too. The "real ones" are OK for a museum piece but damn uncomfortable in actual use even it it's only an 8 second dwell time.....
