grommets

Has anyone determined the part number on this particular grommet on a 1991 80 Series? Looking at the diagrams I can’t determine. I always try and find myself before asking the experts here. Generic ones are too thin for the thickness of the firewall. It’s round. 1991

Hello All, So I realize this VERY minor, but I will pass along all the info I come up with for our Pigs so..... I found these grommets at McMaster-Carr for the front vent pulls. They only come in blue, which is OK for me coz Wilbur's blue & white, but they fit perfectly. I had to buy a bag...
