I have a 1966 corvette that is missing the Blower Evaporator housing box thatwas located on the engine firewall. I have some of the old parts from the box but not all and am wondering if there are any chev drawing of the original specifications so one could be fabricated or if anyone knows where I could find one of these.

 

Ya might try www.pacvette.com , they are a Vette wrecking yard. They just might have that part.
