AC under dash replacement defroster duct assy - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have the complete AC system that I took out of my Dad's 68 to install factory AC. It was installed in about 1969 and came with a defroster duct that allows the under dash unit to sit closer to the firewall, giving more room in the cab. Anyone wanting to install an under dash unit could use one of these. However, they are obsolete. I am going to sell the complete ac set up with the defroster duct, but before I do, I was hoping that there was someone on the forum that could make copies of the defroster duct for any of the members of the forum that wanted their under dash AC to set closer to the firewall.
I would be glad to send the one I have (on a loan basis) to anyone who believes that they could make copies of it. The attached photos show the difference in the original and the one that the makers of the Mark 4 supplied with the AC kit.
