I found mine in a parts car at a used Mustang place. I see them often on Craigslist and ebay. Classic Auto Air has them available as well. Call and ask them if they have a used case available that you can buy along with their new High efficency Evaporator. The rebuild is pretty easy although you may have to make some Fiberglass repairs on the case which re often cracked. You'll need:
67 or 68 Case (They are different but interchangeable) BTW they are available New
Blower motor asssembly
Defroster assembly (Available new)
Side vents (Available new)
Control cables (Available new)
Control Hose (Available new)
Vent Hoses (Available New)
Hose retainers (I made my own)
Water Cutoff valve (Repros available)
There are lots on Ebay although the prices may not be cheap.
67-68 Ford Mustang AC/heater box & plenum with motor, C7ZZ-18A409, EXCELLENT | eBay
I found my '67's box in a '68 Cougar in a salvage yard. It amused me at the time that the old Mustangs there were stripped naked but the Cougar was largely untouched as it was sitting in their "Mercury" section. (Or I'm guessing that's what happened.)Specifically where did you guys find your original evaporator/blower cases?
Technically it is an evaporator, but the average guy calls it a heater box. I found it was hard to locate on eBay, you'll have to try different names.Thanks guys. I've been searching "evaporator" and not for a heater box. I suppose I should start using the right part name. DOH!!! :lol:
That was my feeling as well, and nothing fits like a factory partSearching evaporator gets a ton of replacement coils, good to see they're still making them. The install of an original (or repro) doesn't appear much different than the Classic kits. The generic kit for a grand looks appealing if I wasn't trying maintain the stock look/parts. The mod won't match my Marti Report but the report isn't driving the car in the summer in Vegas. Rebuilding 67-68 cores at least keeps it closer to what came off the line.
