I went through my reprint of the factory parts catalogue but was unable to find a part number for the four vents that drain the boot at the front on the boot floor. Anyone have a part number. Here are photos of the rubber vents.

 

I just dealt with the same issue. No part # and no help at dealer. So, recalling my youth and drilling holes thru firewalls for various reasons, I found at my local NAPA store acceptable rubber plugs that fit perfectly. They are simply round, not the square shape of the OEM plugs, but do the job nicely.
Good luck, David

 

I have the same problem with the battery exhaust pipe grommet. It has also split. I cant find the right one either....

 

.I have a set from a 1994.
They have short right angle tubes not the trapezoid.
I think they are improved from the 90's design
The tubes are less likely to let water back up the spout.
Contact me with text or call to 650-455-1110 if you want them.
Measure the body hole size so we know we are talking about compatibility.
I don't visit the forums as often as I used to.
