I need to re-install my speedometer cable (including the outer plastic). My firewall grommet is pretty worn so I would like to replace it too. The grommets are sold by many suppliers and are basically the same. The issue is that the hole in the original style grommet is much smaller than even the smaller end of the speedo cable. So, how do you get the cable through it without cutting or damaging the grommet? Can you lube it up enough to get the cable to go through or ??????????????

I've seen some new grommets that have relatively thin rubber and those I can see stretching (maybe), but they don't look original.


Thanks

I always cut a slice thru 1 side of the new grommet on angle, then put it on the cable and then I use a small dab black RTV to seal it.

Yup, thought of doing that too. Just seems a shame to bugger up the grommet.

When I did one like that I used the tapered plastic end of a tube of silicone or something. The end starts of pointed and then of course gets large enough to slide over the small end of the speedometer cable. I think I put some Vaseline or something on to help it slide. It went on real nice without damaging the grommet.

Great idea. I'll give it a try.
