Just an issue I had come across with my 46, the PO had put in a newer 235 and it had the newer water pump. They moved the radiator forward ( butchered the support frame ) so they had clearance between the fan and radiator. Problem was when the front clip was bolted on the radiator fill cap was up under the front nose. I had to check water with a small mirror and and try to fill it with a small hose and funnel.
I have it tore down now and have put a adapter plate and short water on and will be moving the radiator back to it's original place.
