Hi Mark, The heater boxes are not the same. The opening through the firewall is larger on an A/C car, so it won't bolt up to a non A/C car. The non A/C boxes are quite easy to find also, as I believe 60-64 are the same. 300ly, Don ----- Original Message ----- From: Knutsen.Mark <Knutsenm@xxxxxxxxxxxx> To: <Chrysler300@xxxxxxxxxxxxxxx> Sent: Monday, October 25, 2004 9:23 AM Subject: [Chrysler300] Firewall Heater Box - 1961 G Is the heater box on the firewall of a non-A/C car the same as the A/C version? If they are, will the A/C version work on non-A/C car?
