There is a Tuna Tank 1/64 die cast done by GREENLIGHT celebrating Daves being the Host for 40 years of the SEMA Banquet. There are a couple on Ebay for anyone interested(not by me) One of the few cars I will leave in the package.
I'm hoping that the NHRA channel on Roku etc. will show the Wheels of Fire movie that Big Mac hosted back in the 70s. It was on YouTube for awhile but was incomplete. At one point he drove up to the camera in an altered (an early version of the Tuna Tank ?
