Try McMasterCarr. They have an online catalogue and sell in small quantities. I used a standard plastic hole insert found in most sizes at electrical supply houses.
They are designed to protect wires from metal edges when running wire without conduit or flexout of a box or panel.

I suppose you could take some rubber hose, say 3/8 inch or so, and split it lengthwise...drill your hole, and slip the rubber hose over the edge, then trim to length....Home made grommet for any size hole!

1inch was the biggest i could find so i put 3 in the firewall, now i have plenty of space to run numerous lines and whatnot .. and it looks like the factory put them there;)

jugdish35,
Where did you get your grommet ? I opened the hood and looked at the back of the firewall just to the right from center there is a spot to drill hole. The factory uses that spot for the PTO harness I probably need a 1 to 3/4 inch outside diameter grommet with a 3/16 to 1/4 inch hole to route the A2 cable through the firewall. Only thing is what is the thickness of the firewall sheetmetal ? The website I found grommets on needed the information to determine what grommet they had for my application.

Just go buy some 3/8s rubber hoes and split it cram the split over the metal and go around the hole.

The firewall thickness is very thin, suprisinglly thin, when I drilled my 2" hole and used some sliced fuel hose as a grommet I cut through it like butter.

Go to any Lowe's or Home Depot and ask for a 2" PVC compression type strain relief (they also come larger and smaller). You cut your hole, put the Strain Relief through, and put the locknut on. That will give you the 2" hole, it will keep everything in place, and will seal around it when the outer nut is tightened. Good Luck

What blkdmax said... call an industrial seal distributor/ rubber company. There may be an order $$ minimum, but you'll have exactly what you need instead of a jerry-rigged (not that there's anything wrong with that) solution.
We buy lots of our grommets from these folks:
