Motor Plate and Pulleys...
One of my side jobs a few years ago was to put a big block in a dart using a set of elephant ears,and what i did to keep cost down was i measured the thickness of the plate and took the water pump housing to the machine shop and removed that much from it, so when i bolted the water pump and plate onto the block everything was at the correct location to run stock pulleys , alt, and p/s pump, with no aglinment probems, and it costed less that $50.00.
