Searching for Wildfire. Custom 1967 Mustang.

I am searching for a 67 Mustang convertible that was featured in PHR magazine in the mid 80's. The car was a custom that was shown on the ISCA show car circuit for several years. Last known location of the car was the Alamo Car Museum in New Braunfels, Texas. The car was sold and the museum was closed. This car is one of a kind with twin turbos and Gurney-Westlake heads. Custom yellow paint and every nut and bolt was either chrome or gold plated. Any info on where this car may be is greatly appreciated.
