Runum,
You did have a little help on some of the cars, like letting little brother hand you a wrench, socket or what ever else you needed under the car.
Then as little brother got older and wanted to help more, little brother got to do the dirty work under the car while big brother worked the top side. But little bro didn't complain because he was learning alot, like how to install a moter in a VW when it is freezing cold.

When Runum says he built the car, there was not a bolt on the car he didn't touch. And to his credit, mechanical failures didn't happen very often for the abuse he was instilling on the machines.
