...oh, one other thing...I did add both of those lines on the thermostat as -6an.

The top is for the 90* fitting is for the overflow lines, which is perfectly fine being small.

Should I change the -6an I added and make it -10an? That is for the line that plugs into the tstat housing and goes over the tranny and into the firewall plug...what is that line for, anyways? Is it fine being -6an? Is it a bypass for the thermostat? It doesn't seem like it goes into the motor at all...and there are 2 lines that are maybe a -10an relative size right there, one goes into the radiator. Why do those 2 lines go from the thermostat into the firewall and back in the radiator for??
