I want to try a good flex type / regular fan on the dart. (ive also got a summit coupon sitting here...)

So...guys with a flex fan + aluminum aftermarket radiator + BB A body + factory style water pump and pulley =

what size fan spacer do you have ?

I have 3.75" from my pulley face to the rad .

Not sure the depth of a flex fan....

I just dont want to order the wrong size spacer and have to pay shipping twice !
