So today I went to my local JunkHeaven and found 2 seats from a 93 Ford Van but when I looked in the back I saw this bench seat that, you can tell, didn't belong there. It was old school vinyl blue (IN GOOD SHAPE) and it had seat belts. One thing I noticed was that at the ends of the bench it had armrests and the armrests had those lid pop-up ashtrays.
I was so happy to see it and since I have a 75 E-150 shorty with a brown/tan and black and old ford blue color scheme going on, I bought it.
Most of the old school vanners (not me LOL!) can identify them from sight. I lucked out and found Ford tags on the seatbelts of the tan bench I'm giving away, and Ford stickers on the captain chairs I just bought. Look all over the seat, under it, on the rails, inside the seat belts, etc. for a tag or sticker of some sort. Also the older GM buckles usually had a GM logo in the push button, and the Ford buckles that I've seen had a star type design on the push button.
