I need a driver's seat for my '72 Dart. The old bench seat is in bad shape, looks like crap, and is extremely heavy.

Something a bit more comfortable than the plastic "racing seats", for street/strip use, but don't want to break the bank either.

Unfortunately I'm somewhat gravitationally challenged (6' tall but 46 waist, 54 or 56 chest). The sport seats I see at Summit and others look like they'd be awfully snug on the sides.

What are the bigger guys/gals sitting in?
