Default 3/4 fan spacer ?

Anyone aware of a source for a 3/4 cooling fan spacer ?

I currently am using a 1 and am attempting to maximize my cooling system.

Thank you.

You can find them on Amazon, or you could likely have your current spacer milled down, but either way I think it's doubtful that a 1/4" reduction will make a difference. Have you considered installing a clutch style fan instead? That would allow you to achieve a correct fan spacing while also freeing up HP, which fixed fans are proven to kill.

There are also clutch fans with different length stems.

Fan clutch with the correct blade was the biggest improvement I made regarding cooling for my last a-body. I have one now on my GTO that’s hitting the road soon.
