Speedo cable grommet - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**rgunlock** · 09-10-2016, 02:57 PM

Where can I find one? It doesn't appear that anyone sells the speedo cable with grommet installed, and a good deal of searching has turned up nothing for the grommet itself for 73-87. Anyone have a source?

Do you mean the retainer clip that hold it in place behind the cluster?

If it is, LMC had them.

Sorry, no I should have been more specific. I mean the rubber grommet that goes into the firewall where the speedo cable comes through it.

I thought there was a chance that was what you were referring to. Yeah those seem to be hard to find. Do you have your old one, to get size dimensions from?
There is this place that has grommets:

There is a speedo cable with the grommet on Ebay, if your really in dire need of a grommet. It's off an 84.

Appreciate all of the pointers TKCR. I do have the original grommet, but cut it to get it off of the old cable. It has a metal ring embedded in the rubber, and 3 tangs that look like they hold it to the hole in the firewall. It is too far gone to hold in there now since I cut the metal ring.

The cable is about 5/16" diameter and the firewall hole is about 1". I can probably use a grommet from the site you provided. They have one with a bore diameter of 3/8" and a groove diameter of 1" that may work if I can get it over the fitting on the end of the cable and get it seated in the firewall. The groove is 1/16" so likely to be pretty tight.

The last time I got one was at the Dealer they still make then for the GM full Size Vans.(grommet for the speedo cable throw the firewall) I think some where between 2010-2014 GM full Size Vans (grommet for the speedo cable throw the firewall). If I find the bill with the part # I will let you know.

Anyone ever come up with a part number for this? I’ve gone through the GM parts manual but I must not be looking in the right spot
