Anyone have the Volvo Penta part number for the old Prestolite "Clip on" style distributer cap? 5.0 litre Chevy V8. 1982 It's amazing, cant find it on line anywhere. In fact most places selling caps dont even specify if it's the Ford or Chevy 5.0 litre! If you have the part number they are ready to sell you one, if not... they dont seem to know much at all!
