Rubber Seat Spacers

Thats a good question. When working on the used car lot we sold to a few short (or should I say vertically challenged) ladies that wanted spacers under the seat and I was soooo glad the factory used long bolt studs to accomodate the spacers. Then there was the old man who brought back a Crown Vic cause he couldn't wear his hat in it.
Some cases where the spacers went under just the rear of the tracks to tip the seat toward level reducing back pain. Seat spacers make happy customers ? Far as I know thats the only reason for them.
