Just looking for some clarification on a few parts...

Cooling fan, were they only equipped with a fixed fan? Or was there an "HD cooling" option with a clutch fan? What would be the correct size, blade count, and part # - if applicable that I need?

The radiator top plate, 3 bolt only? Or was a 4 bolt version used if one ordered HD cooling? Mine is MIA along with several other pieces.

Does anyone have the part # handy for the crank pulley, it would be a single groove for LWP.

Lastly, the air cleaner assembly. I am under the impression that the manual transmission cars like mine has a smooth snorkel with no pod for the heat stove assembly. I believe it should look like this:



The car in my sig was mostly complete in 2007 when my father sold it. I was able to purchase it from the man he sold it to last February - however he had removed the engine & transmission, and lost some of the parts... pulleys, brackets, air cleaner, etc.

I appreciate any help in confirming exactly what I need to put it back together.
