Since the photo quality is poor....the location is correct, in that it is Laguna Seca, most likely in the early 1970's (possibly around 1971-72). The #99, upkicked side exhaust, chopped down plexi front windscreen, 427 wheels front and rear, AP class designation, white exterior color and what looks to be a 427 competition gas cap on the passenger rear....looks to be pointing out that this is the Dick Workman 427 Cobra (3137). What number is your Cobra?
