i did shoot a high 1200 rpm video during my test, here it is:

can see the oil pump start to turn with the rotation near the end, but no mess

Talked about this a few times, and I am now going to venture into fabricating a mold and trying to have some reproduced. Not sure what they are Technically called per the MPPL ? or the part number.

I looked back through my pictures and found a shop from the PO that shows the Pedal Seals. but i can NOT find them anywhere in my stash. luckily beachbum graciously provided a picture he had as well. since i am waiting on my engine to get back from the shop, and not much else on the car to rebuild right now, figured i would try this out.

My plan is to sketch them out, then 3d print one and do a test fit, hopefully get the shape and concept down and then will get a mold made and then have a few sets produced.

Have a few questions, since i can not find my set, really need to get some dimensions and general data about them.

1-were these 1929 only or other years as well ??

2-left and right the same, just mirror images or two totally different designs??

3-they look to be made of a rubber, are they soft (floppy soft like silicone), hard (not very pliable), or medium (like a standard rubber window gasket)??

4-seem to have a metal plate inside, is this a SOLID metal plate, or a wire mesh of the sorts ?? how thick the the metal ? is it one piece of metal or a few sheets with separation/rubber in between.

5-how much robber overrun is there on the metal. how much robber after the metal.

6-dimensions dimensions, dimensions... basic opening, size, shape, corners.

7-looks like 10-24 bolts were used to hold them in, or were they 1/4-20 ?? looks to be flat head slotted, assume they go all the way through with a washer and nut on the backside. and they go through the upper and lower plates on the toe/floor boards.

assume they do NOT seal the hole, but more so fill it in some, did the rubber touch the pedals ?? was slot basically the same size and shape that the upper& lower plates leave when put together ??

any other details, information would be appreciated. also if anyone is already making these or know someone who is, let me know !! i would like a set or two.

did a sketch based off the pictures i have, and digitizing the upper & lower pedal plates.

i then 3d printed a prototype out, printed one with a larger opening, as i was uncertain if the PLA (material i am 3d printing) would snap when i tried to flex it around a pedal shaft. luckily it did not, so i marked it up drilled a few holes, and seems to fit pretty nice on the plates. the white area is where the seal is smaller than the opening of the plates.

i am happy with my first prototype, once i can get true dimensions from someone with one in hand, i can adjust accordingly. they  are currently scaled off the pictures.

i want to make sure i keep some meat (material) between the openings, and considering there is a metal plate in there as well, need to make sure there is rubber all around the metal as well to cover and coat it. want the metal fully encapsulated in rubber, so the pedals rub on rubber if they rub.

both prototypes side by side

finished prototype with holes located and drilled

prototype laid over the upper and lower pedal plates

close up

prototype under the plates to show difference in opening, plates vs prototype

Did some digging in the MPPL and found it !! thanks for the hints VCCA Member beachbum ? did some random searches for 3 digits the 194 found it

looks like it was a 1929 year only thing, it is listed in my 1929, 1929-1930, and 1929-1932 MPPL but only for the 1929
