Firewall block off plate
 

I plan on installing classic auto air in my Tempest towards the end of the build. I have contacted them about kit prices because I already have the compressor because it came in my accessory drive kit. Since the front end is off and the firewall is going to be painted I want to install the heater box block off plate now so they don’t have to pull the fenders and all that Jazz later. Can I use any brand firewall block off plate? I am using classic auto air because of the hoses being routed thru the firewall and not thru the kick panel. Does anyone have a recommendation on who has the best block off plate? Anyone used classic auto air before. I have used it on a 58 and 59 Chevrolet because I feel like they make a superior product to vintage air but on those cars you don’t have to remove half the front end to do the work. Any advice would be appreciated.

Anybody

With my vintage air install I'm using the original blower box as my block off plate.

I think FabCraft had some of those as heater delete plates. Don't remember years.
