This is the radiator connections, compare them to yours now and you'll see they are shorter and smaller and at different angles.
My upper connection doesnt look too hard to make. I just need to adapt from the ~1" outlet on the thermostat to the radiator neck. My radiator neck looks like it's been squashed a few times. I'm hoping I can tap a 1" OD pipe in to the neck and solder it in. I see the tanks on this are brass, and I thought about actually moving the inlet and outlet, but that's probably going to be more of a pain than its worth.
In other news, it looks like the dynamo that came with this will fit under the hood. My alternator showed up today too. I'll tackle that and I get the cooling system and clutch sorted.
