1967 Dodge A-100 Hot rod sort of rat rod build thread.

Right. I was thinking about the fitting, not the block? That's gotta be a .25 id or so, yes?
The size of the fitting that typically would go into the trans housing has a pretty tiny ID. The rear lube fitting on a 4l80 has to be way less. If it start life as -6, necks down to fit through the case, then necks down again to get to lube through the rear support.(?)..
