1968. Rear Side Markers were first required that year and the 69 and 70s looked differenent. The Delmont was famous for sailing over a bridge. Those red seats came off an Olds 98 Regency from the 1970s-80s
Apparently the last time cars came with a bias ply tire was early 1970s! Do you think that this car has really low miles? Unless they just bought new bias ply tires to replace their factory bias ply tire. I'm curious how old the Bondo fix is. Considering it has new paint and the Bondo, maybe it has many miles and they just chose bias ply when replacing the tires or that one was a spare.
