Passenger side wring harness firewall grommet
 

I started noticing that the passenger side floor is wet every time there is a hard rain.

I took a look and found that the big tape-on grommet where the harness goes through the firewall is ripped to shreds. Clearly what happened is that some guy back when just poked a hole in it to pass the amp wire through and eventually that destroyed the grommet.

I can't find this damn thing. The online parts listings are kind of cryptic.

The grommet is 1 9/16, which is a hair under 40mm. No one seems to sell that style in that size. I can find them bigger or smaller, but not that. There is one in Australia, but the shipping is gonna be killer.

Any idea where I could get one?

check wrecking yards. know anyone with 3d printer

This seller has a grommet for a 40mm hole
