Waterneck gasket info needed !

Not that it needs mentioning, check the length of your bolts. One thread too long and it feels like its tight. But its not.
Oh yea thats always possible
I cut a zip tye and measured depth because some Waterheads owned truck before me and entire engine bay was jacked up !!
They had wires jumped and zero ballast resistor on truck Its amazing how stupid & cheap some Humans are.
