Factory Focus-Point Mind-Set Approach
A light when off reading your last helpful post. At least I understand how I got here. This is a new-to-me vehicle so all work is that of a PO. What I know is the engine is a 03 or 04/77 block in a 1972 pig. Now I further realize, I removed a pump and pulley intended for a clutch and matching fan. Instead of a Toyota clutch and fan, the metal fan was used. The hub on the old metal fan had four radiating mounting holes to compensate.
You are correct. From where I am now, here's how I finally understand my choice. Return pump and fan, keep pulley, then source clutch-type pump, clutch, and fan. Or keep what was sent to me, and source pulley. It boils down to sourcing a unicorn pulley vs. buying more parts to add a clutch.
you may want to measure very well and make sure a fan clutch and fan cluct fan will actually fit and not hit the RAD ?
owning a vintage toyota always involves purchasing new and updated parts ......
