Now that I have my powertrain "upgraded", it's time to work on the interior. The stock vinyl bench seat is very torn on the driver's side (naturally) and most of the stuffing is gone. Rather than just put a seat cover on it and forget it, I found a set of bucket seats out of a '91 GMC Vandura. Will these fit without major modifications? I would really like to install them without having to go in from the underside, so I don't have to drop the gas tank.
