Rv2 oil pump spring +ball

Hi,I’m new to this forum,I have a question about the rv2 ac pump I’m rebuilding. I bought this ac pump brand new from my local auto parts dealer,it seized up due to no oil pressure,I did fill it with the proper oil,the problem is that it come from the dealer without the oil pump ball and spring,and even the rebuild kit doesn’t have it.my question is ,does anyone know the spring length and diameter,and the ballbearing size?Since it’s not avalible in any kit.thanks
