Brandon, the heater blank is a pre-fabricated plate that is manufactured by Vintage Air, and is supplied with their 'Sure Fit' Underdash A/C unit that replaces the core in the firewall. I'm sure they would sell you the blank by itself if you give them a call. Be sure and mention my truck, and ask for Mark Hungerback
mark@vintageair.com to get that part.
Who is 'Ken' that you are referring to? I'm not that familiar with first names on the boards.
Jim, this truck has never been on Ebay, unless someone scammed by pics and ran a listing. You never know with Ebay anymore. It was listed on Collectorcartrader.com however, before I decided to consign with B-J.
