hey paul,
nice set up !!
i wasn't going to have any heater or air !! i already had made up a plate like yours to cover the hole! then my wife talked me into both !!!Cry she knows we'll be cruising a lot and wants it for when we take it on trips. i figure i could always take it out later if it bogs me down in HP!

just doin a quick check with DR REBUILD, it looks as only a few seals are interchangable. most parts go from 68 to 77 Cry.
if any one knows otherwise let us know!
thanks for the offer though !

A little wax, and she's good to go!

Joe, yep...yer car is an A/C car. That's good. It'll be a lot less hassle that way. Looks like the stuff you got will work fine, and it appears to be a fair condition. Good luck, and have fun installing it! I would suggest you get the factory AIM(Assembly Instruction Manual) for your car, if you do not have one. It will be invaluable to you in rebuilding your car.

Joe;
They molded the bodies with the heater hole, and they cut out the extra on the assembly line.  I am sure I saw a diagram somewhere in the Assembly Manual, but it seems to me it was somewhere I didn't expect to find it.

To add insult to injury, The hole in your firewall is hacked out more than it should be.  I have a photo of a factory A/C firewall, if someone can help me post it.

Other considerations:  A/C cars only had a vent on the right, and it was vacuum controlled.  Heater cars had two vents, cable controlled.  A/C cars had another hole on the upper right of the cowl, under the fender.  I was stupid enough to not take a picture of that.

If it were me, I would patch the firewall and use an aftermarket system.  It is cheaper and easier, and works better.  I have used the Vintage Air system on other cars and been very happy.
