changing water pump on a supposed \'83 258
does anyone know the difference between a 70's water pump and an 80's?
i was attempting to change the water pump on my 83 258. it is rumored that my motor may be a '77, but i am not sure. the previous owner put the rebuilt 258 in, and i have the reciept, and it says that it was an 83 motor. when i had the water pump replaced a few years back, the guy told me he couldnt get an 83 water pump to work, but one from a 77 fit.
i didnt know whether or not to believe him, so i bought an 83 water pump yesterday, and all the bolt holes lined up and fit great, until i went to bolt on the pulley. it bottomed out on the pump , apparently the impeller shaft is too short? spacing it out with washers doesnt work, it only provides an uneven surface for mounting.
