I purchased a 40 that came with most of the engine in a box. Just got it back from the machine shop and its time to re assemble. *(It has air conditioning likely installed after original purchase) What i seem to be missing is the spacer that goes between the water pump and the double pulley. As it is now, the pulley is off by 1/2" from lining up with the crank pulley. Something's fishy it seems. I'm not used to the air conditioning option or how they space the pulley into line. It is a toyota air conditioning system, but can't believe the dealership would hack up the firewall during installation like this one is. Not sure ill even get the air working but wanted the pulleys to align. Anyone have a 78 with air?
