Again, thanks! | | | | Joined: Oct 2000 Posts: 804 Shop Shark | | Shop Shark Joined: Oct 2000 Posts: 804 | I was going to order my steering column thru floor seal and noticed that the hole in the floor/firewall looks like the shape of the seal for a column shift. And the 4-speed column seal which I will be running doesn't look like it will go up high enough to cover the hole. Are there different holes in the floor when the truck had a floor shift than with the column shift? http://www.truckandcarshop.com/trucks47_59/t47_036.html Brian

Always get a 2nd opinion, especially if I am the source of the 1st opinion.

My impression ios that all the cabs were stamped this way. The present day suppliers of the seal do not sell one that covers the extra opening. | | | | | Joined: Oct 2000 Posts: 804 Shop Shark | | Shop Shark Joined: Oct 2000 Posts: 804 | Ok,  one of you says different holes one says no. At least I think that is what I am reading. I have seen many of these cabs, I never noticed different holes. In fact, I remember seeing years ago how the cab has the "hump" in the fire wall on both sides with the cut out only being on the left. I have in piles of boxes somewhere an original floor shift seal and it looks just like the one at the link, I remember that. So, did that original seal just not cover the hole all the way and they expected some fire wall insulation or OTHER means of sealing the upper portion? If that is the case, I'll just fill that hole and make it round like Chevy should have. Brian

I had a 1/2 ton '54 factory 4-speed but I do not remember if there was a hole in the floor for the 3-speed linkage rod. I will ask the present owner to check it out and will post his reply (if he replies).

Fred | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | I thought I posted this, this morning but I guess not. Brian, I ran into the same thing when I replaced the seals in the firewall on my '50, 3604. Mine came from the factory as a four speed and the hole in the floor is teardrop shaped as was the original column seal. The seal did not have a hole for the column shift. I ordered seals from three different vendors and they all were the round ones which will not fill the hole in the firewall. This again leads me to think that they are all getting their supplies from the same supplier, and I might add, don’t have a clue as to what their suppliers are making for them. It’s just one more example of a lack of interest to the small details. And as long as we keep buying their parts and not complaining they probably won’t ever change it. I have to say that the replacement seals that I did get were well made and were accurate reproductions, that is, if you have a column shifter.
Since the rubber covered steel plate on mine was still in very good shape and cleaned up like new, all I had to fab was the foam. The plate would be the hard part to duplicate and if yours is missing or rusted I don’t know what you could do. For the seal I ordered a sheet of material (sq. ft. of 3/8” foam) from McMaster Carr and cut my own on the band saw. I drilled the hole for the column with a hole saw. Now it fits and looks exactly like the original did. Denny Graham Sandwich, IL
