I am working on a '67 3/4 ton that has the high hump transmission tunnel. It came in pieces, with the transmission tunnel removed and in the box. I couldn't tell if there was a gasket there. Can someone tell me if a gasket sealed the tunnel to the floor, and if so, where to get one? Haven't seen anything anywhere that addresses this. Thanks

From what I can remember, the factory used a type of caulking similar to climate control boxes, maybe the same thing?

People fear change because it threatens what they know, or what they claim to know.

That certainly sounds quite plausible. The other day I was in town and a shop there was working on a '71 4x4. I went over to look to see if there was anything there. Much to my suprise there was a substance in there that reminded me of the foam insulation in a can. Someone didn't like the way their tunnel was sealed.
