Firewall grommets for AC & Heater

I'm installing a 94 Accord HVAC system in my 37 Buick.
I need 2 inch inner diam and 1 inch diam grommets for the AC & Heater lines that go through the firewall.
1) What are best firewall grommets for AC & Heater lines?
2) Can I use any common wire grommets or do I need parts made out of special material to handle the heat and cold?
3) Should I go with a large OEM style grommet with two holes or would two smaller grommets work?
