Short Shaft Fan Clutch

I am using the Jag clutch with the Mopar Performance 5 blade fan. I have used this set up with zero problems over 4 seasons. The 5 blade fan moves air and is a bit lighter than the standard Mopar 7 blade clutch fan. I purchased the Mopar 5 blade fan from Mancini Racing. I will switch to the new clutch when the Jag clutch fails. It appears Mancini Racing does not sell the fan anymore, but Summit has Dorman 620-054, which is published as a direct replacement for the Mopar 5 blade fan.
