i have a f100 1956 truck it has a c2ae block a evb 8505 d water pump with the high mount fan. i cant see the numbers on the timing cover but it has the motor mount base on it .the motor sits low and  i want to put p/steering and have to line the pulleys i have all the pulleys and the right harmonic balencer. i need to get a water pump to run my w/pump pulley and center the fan with the radiator. or do i have the wrong cover? thanks for your help como se yama

Be aware that there are two basic timing covers in regards to water pumps and fuel pumps.  The earlier covers have a smaller water pump and those pumps are more difficult to find when replacement time comes around.  The smaller water pump timing covers also use a different fuel pump which can be identified by the 5/16 X 18 bolts that hold that particular pump to the cover.  The larger water pump timing covers uses a fuel pump that attaches to the cover with 3/8 X 16 bolts.  Once you've got a handle on the timing cover, then there are two pulley hub stub sizes on the pumps.  The cars used a 5/8" stub while the trucks used a 3/4" stub.  Either of these can be made to work as long as the appropriate water pump pulley is being used.

Didn't the cars us a 5/8 stub and trucks 3/4?

John.  You’re right on the sizes.  I’ve corrected my numbers in the post above.  Thanks for catching that.
