Champion radiator install with twin electric fans

Here's mine, the 22" radiator size kinda limits whats available. I'm just guessing here that you're '67 has that size too, but not sure.

I'm an old glass guy so it was easy for me to run some silver silicone around the rad/shroud seam that looks like aluminum weld and seals the gaps.

I have both fans running through a 30a fused relay each. The drivers side runs off a temp sender on the intake, the other side is switched from the dash. I just keep an eye on things when stuck in traffic, if the temp creeps up I just hit the toggle and it cools right down. Most of the time it only uses the left side fan.
