Just curious...if I were thinking about adding a five blade fan would I need to change the spacer behind the fan?

 

Nope, should be the same.

 

Cool...I will have to look into installing the new fan and shroud I bought this weekend. Someone gave me a gift card for Christmas and I couldn't think of any other Mustang related stuff I wanted in that price range and I've been meaning to add the shroud for a long while now.

 

Have the spacer dimensioned so the fan is half in and half out the shroud
