Firewall hole what? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Next to the steering shaft is a hole, I think must be for a manual shift rod. My truck is an automatic, but hole is there. Could this have been a manual shift at one time, or is there a factory delete plug or cover?

Someone posted this sometime back. You probably can make one or order some rubber plug that used to go in those holes.

It should have had a metal plate with rubber backing held on with 2 screws covering it up for auto.

Thanks for the input . Clutch linkage, that makes sense.
So is it a rubber plug? That fills the hole.

Posted my replay at same time you answered.
So I'll look for a metal/ rubber plug.I wonder if it might be one that has metal fingers that snaps in place. I didn't see any screw holes in the body.

I will take a picture of an extra one I have sitting around and post it so you can see what it looks like, If no one else beats me to it. And it goes screwed in ...
Edit added pictures Here are two pictures of my fire wall where you can clearly see the holes for the two screws...I forund theses pictures here on the board from other posts So I will still get you a picture of the Metal plate that goes there some time today.

Since 8door's truck is a 68 the hole cover would have been a plastic snap in plug. The plastic plugs are not available so the metal plug can be used. The two mounting holes will have to be drilled. #6 hex head sheet metal screws 1/2" long is what is used in the 71-72 trucks.

Well firewall info is good

I'm learning more from the pictures than just the "clutch linkage hole." Sounds like a conversation with a Proctologist
