Hector Rebaque, well-known for his very successfully modified Porsche racers, acquired the original chassis for this example from internationally-known racer Al Holbert. After substantial modification it was first raced in Mexico City, by Rojas, Rebaque and Van Beuren. Following, it had a long history as a competitor in the 24 hours of Daytona, at Sebring, at Road America and Puerto Rico.
