1968 GTS 340 with Carter AVS 4966S

I don't have a '68 Dodge shop manual.
This is the '68 Plymouth manual.
The spacer and fan may be correct. The spacer you can measure.
For the fan, functionally, the clearance is most important.
Someone here should know if that blade is correct for the non-clutch fans in '68.

On the four blade fans (used on the 6 cylinder engines) the tips are bent, so they all have differences in design detail. I don't know them all.
