customer wanted to put dual webers on his A20A1. he sent me a gasket, so i helped him out. i had probably somewhere around 70 hours into these including design, programming, machine time, welding... i chose to do them because there was no need for injector bungs. that made the project a lot easier. he was also very very specific on providing specs which also made it easier. he was patient too! in general he was a great customer.
