66 Chevelle SS396 & 66 Chevelle 327 Convertible.
Just got through putting a rebuilt 2004R in my 66. Running down oil leaks. It seems the only one left is this fitting for the lock up converter switch. I am thinking I should take it back to the rebuilder. Photo os not the best; but it is leaking bad enough to make a mess on the floor every time I drive the car.
