There is no real minimum wiring in this convertion . You need to remove the complete GM engine wiring harnesses and mark the connectors . And try not to damage any connectors or sensors . Also you will have to use the Camaro fuel tank or one like it . You should be able to use the GM 5 speed . It has a clutch master and slave cyl that is easy enough to install in your Rambler . I think this is a cool conversion that will work out well . Save as many parts from the Camaro as possible . You will need more of them then you think .
