Ah....so the customer breaks down...opens his wallet and purchases the top of the line full mod just like you recommended. Controller,machine,fixtures...everything top notch! ^ months later the car freewheels into the overhead full speed with passengers! What do you tell the customer in that meeting the next day? Just playing Devil's Advocate! I'm not disagreeing with you just stating you never know when an accident will occur and the customer has to make the decision on his piece of equipment. We only maintain it we don't own it. In closing "Why doesn't the Codes take care of these problems" In 1927 there were no seatbelts laws yet if you drive an older car that vintage and get pulled over you better be wearing a seatbelt or you get a ticket? That's the Law!
