The seal around the steering column is actually a sandwich with the felt in between. I believe on your truck yours could have been rivited together... The plates with a felt liner in between.
If you have a 4 speed, your right, the seal I have will not work.... Although I don't know why.... As long as the hole in the sheet metal is the same...
I had to build my own felt sandwich although I don't think it's correct for my year. Can't find a picture of one to be sure. It's held together but some carriage bolts made to look like rivets (not shown)
