I just finished addressing the same issue on my ‘59 235 in my ‘52 1/2 ton. Using my existing 10-SI alternator with a new 5/8” pulley, I bought a new water pump for a 216, the water pump relocating plate that Tim suggested, a new alternator bracket made for the 235, a used 216 fan blade, a used harmonic balancer with a 5/8” pulley and finally a new 5/8” fan belt.
Although none of the work was difficult, but it was allot of work but worth the effort. My radiator is now back to the stock position, the fan is properly centered on the radiator and now the whole setup looks stock.
I choose a 5/8” pulley and belt because it looks stock but you can also go with a 3/8” setup. Click on Tims link in his post to get all the info and options.
