I recently purchased the booster and pedal combo from here for my 58 Chevy Fleetside . I wonder if anyone else put this in there truck.Is there a location on the welded bracket that the brake light switch goes into.I realize I must remove the existing dash board support but I am lost after that. Help. Is there an instruction sheet for these I did not get one .Tony [ PS its my first build ] Any help would be greatly appreciated.
