I just gave the water pump adaptor info to another member. LINK

My ‘52 3100 Has a ‘59 235 in it from a car with hydraulic lifters. I installed the adaptor plate from fellow member Pre 68 Dave. You'll also need to install your
water pump, fan and harmonic balancer if the 235 pulley (fan belt) is a different size.
