FWIW, there are three different 'stock' seats (and maybe more!) that come in various years of Panteras. IMHO the earliest examples from '71-72 can be made to comfortably fit nearly any human being. The seats I like are the ones in which the backs completely remove with 4 bolts; the rear fastener system can be easily modified to change the seatback 'rake' which will accomodate most comfortably. Reupholstered examples allow my aged 6'2" body to drive 6-8 hours at a stretch and change with my 5'4" wife who also has no back or seat problems. Most aftermarket seats often simply do not fit well in the Pantera which has rather narrow seat areas. Rule of Thumb: if you are 6' or over, avoid ALL seats that have thick backs or bases; both limit the adjustability of whatever seat you choose, and carefully measure the overall width of the donor seat before buying. What fits the drivers side may not fit the passenger side- or your co-driver.
