47 accelerator pedal grommet

[mudbone]

I'm replacing the accelerator pedal and rod in my 47 coupe, and the large hole on the floor board where the pedal rod passes through had no grommet or type of seal. I've been on Macs Web site and used every combination of description I can think of to bring it up. I've also checked the green bible and cannot find anything. I know Henry wouldn't have left the hole open. Anyone have any info as to where I might find one or a description of what it's called ?
Thanks in advance.

Does the 47 have a removable wooden floor board like a 40? If so, here's the 1940 car toe board. The hole for the accelerator rod that attaches to the gas pedal is an oval shape about 1 5/8 x 1 1/8 inches. I think it has to be that large to allow for the movement of the accelerator push rod. However, I do notice that the reverse side of that hole is recessed,as if there was at one time a rubber grommet or seal of some kind that was glued to the recess. I bet it was something like the 1932-48 brake pedal brake pedal bumper (91A-2476) that fits around the brake pedal arm. If you find that the brake pedal seal works, please let us know. I bet it will work. It looks like the one on the right here but the clutch pedal seal could also be used in a pinch. I also need that seal if one exists. Thanks.

I tried that pedal seal on the accelerator on the '40, and it needed some rework to clear the arc of the pedal rod, and I couldn't figure out how to keep the pedal seal in that oval shaped hole in the back of the floor board. So I too would like to find out if there is solution.

A lot of carry through spots on aircraft firewalls have a thin piece of micarta (like a small piece of circuit board material) that floats over the hole on the uppermost side. The rod or shaft that goes through it keeps it supported and it can move a little side to side to compensate for irregularities in the movement of the shaft.

Ford likely just used a piece of felt or perhaps jute material that might be under the floor mat.

Rotor, On at least the '39 - '40 Ford passenger cars Ford did use a piece of heavy (dense) felt. It had a slit in it that allowed the rod to move fore and aft.
This felt was stapled to the underside of the board - within a recessed pocket of sorts.

1947 Ford (cars) had a sheet metal floor vs. the wood seen in previous years.

So that's the answer to the '40 seal, dense felt with a slit. Thank you Kube

They do have a boot for the 49-50 pickups , saw it advertised in lmc trucks was thinking of trying it. In case anyone else is interested.

I had a quarter inch thick piece of heavy rubber and cut it to fit the recessed hole in the floorboard
. I then drilled the center hole a little larger than the pedal rod to allow the rod to move easily. When my new pedal comes in, I'll test fit and if its OK, I'll dab some rtv on each side to attach it. That should resolve my open hole situation.

A single hole in the rubber won't work.
The rod when attached to the pedal travels in an arc, that's why a slit not a hole.
