Mr Wrenchbender, Sir,

So if I wanted this to be correct for 1966 factory correct, I should obtain a therm house that has a temp sender port? Another question along that line, would a '66 have had the cooling sytem bypass? And does that hose come out of the therm housing or the water neck? Lastly, I have seen "vertical" and "horizontal" water necks for these engines. Which came with which? THANKS!
