firewall grommets

[Dartgame]

I searched the site looking clues about what others are using to replace their speedo and emergency brake firewall grommets on a 52 Plymouth. No luck.

The hole size is about 1.20 ", which I assume is probably intended for a 1.25 hole size grommet. I've looked on the internet, and various mopar, & brand X supply houses. Trouble is most of them do not know the dimensions of the parts they sell. ( typical answer - well it fits a 61-64 chevy...ugh, some have been kind enough to measure them for me on the other hand).

Only found some from American auto wire grommets with a thick crosssection and relatively smallish center hole. I ordered a pair of these thinkin they can modded to work. 

Anyone have some suggestions ?

I used radio antenna hole plugs (from a two-way radio shop that worked on lots of police and municipal vehicles) in the firewall of my '52.   Works well.

You might check Harbor Freight they sell an assortment  kit of rubber grommets.

Don't know about car grommets, but a while back I found these for my B4B.  They had LOTS of sizes and shapes to choose from.

Thanks - my brother works for a municipal vehicles dept fixing radios and such. I'll ask if he has something like this...

Check out Steele Rubber catalog for grommets. They show in the front part of the catalog  lots of grommets with inside and outside as well as opening size. Prior to finding some original type grommets for the firewall, I found in the Steele catalog in the Buick area grommets that fit the hole you have and were without a center opening. Using this you could use a punch for whatever size opening you want. You might also look at Chrysler grommets for the 50s because they also have the same size  firewall holes you have.
