Parking brake cable retainers & grommets?

I've found an acceptable (to me) replacement grommet for the firewall to protect the parking brake cable. It's a Dorman rubber products #42064 PCV grommet, sold at Advance Auto Parts under the "HELP!" product line. Almost a perfect fit, and doesn't look too bad either. Really had to work to get it over the end of the outer case shield (sprayed the hell out of it with silicone spray lube, then worked it around carefully like putting a tire on a rim...) Hope maybe somebody else finds this an adequate solution. For $2.00 instead of $21.00, it works for me!
