chev235:
I just got a short shaft pump from Patricks and he included a 1/4" spacer to put on the end of the shaft (after I put on the pulley)which brings the fan closer to the radiator and clears the balancer. I haven't done it yet...I just opened the box!
I was/am going to use the 216 fan on my 261 as well. What did you hear about the 216 fan?
