Hey Jeffrey, My 66 Chevy wash pump petered out and I found a nice one in the TREASUES TROVE (junk yard)from a 80 model VOLVO . I know it's not chevy but it screws onto the top of your plastic bucket and hook up the wiring on a contact switch , the hoses is under the motor and the wash hoses go to your mounts spraying your windshield for as long as u hold the switch , not just a timed action.Plus its black and looks factory to the untrained eye. Hope this helps.
