Fan Clutch

Doing a little searching on the fan clutches used on 65' and 66' ser. 10 thru 30 trucks, with HD Cooling/Rad., and air conditioning. Below is a copy of one page for 1.050 Clutch Assy.- stud. Engine Air Fan.

Shows two different designs, 65' with design 1 ( 6" DIA.) part number 3862159; and 65 and 66' with a design 2 ( 7 1/8" DIA.) part number 3883158. Look like 65' had both designs, and 66' uses 2 nd design
