I've got a 67 camaro with long water pump does anyone know what pump and bracket i can use other 67-68 camaro or firebird does the 70 - 81 camaro interchange

68-74 Novas use the same subframe as your car. Many others probably could use the same pump, although the brackets for a Chevy engine would be different from Pontiac brackets. Check with a wrecking yard for an interchange. Most can give you a printout of what fits.
