The Reliability run on Friday is open to all pre 65 vehicles. It is a tour around the Colorado mountains. I had almost as much fun on this run as I did going up the hill. One thing is this the actual hill climb on Saturday isn't timed and it is just for fun recreating a race that happened in 1954. They do not hold hard and fast to requirements like the TROG guys do. If you have any questions about eligibility I would contact Nick's Garage. I have participated in the Hill climb the last two years and haven't has any problems. I run an alternator and a T-5 on a model A engine. Obvious later model engines wont fly. They usually announce dates for the next year at the LA roadster show. Hope this helps.
