Keith and All, After rechecking the hole depth, I found the hole in this head was all the way into the water jacket. It looks like the casting thickness in this area is .875 so I would not drill deeper than .500 full diameter to prevent breaking thru the casting. Jim Bartuska Niles, Mich.

If I do go with the aftermarket/aftermarket/<WBR>underdash solution, I would really really wa vintage look on the interior evaporator unit, as well as under the hood. Another question - can anybody tell me this? If I do put in a factory compressor and I have to drill/tap the head for the bracket, what is the size and depth of those holes and just how thick are the bosses there? I really wouldn't like to create a new coolant drain.
