<VV> 1964 engine fan questions

[Frank DuVal]

There is no difference in the COVER between road draft tube and pcv 
system. Both systems use the same hole in the side of the cover. 
Different exterior plumbing makes the change.

> Right again, the complete late or early top cover/fan assemblies can be interchanged (I've seen '64 fans on lates too).  The bearing can be pressed up or down to adjust the fan to shroud gap.  Heating the cover makes it easier to move up and down.  The big difference in the cover is the PCV tube vs. road draft, but you can swap that or convert as desired.
