I put our buddy in touch with canadianponcho member GC as he has a bunch of cars.  As of this afternoon he was on his way to see GC, hopefully that proves fruitful. 

I figure 67 & 68 small block power steering brackets are the same, possibly changed in 69 with the move of the alternator to the passenger side.  Not sure about 65 & 66.

I looked to see if I had any brackets and all I have is one set on my '67 Laurentian which I tolds Gord he could borrow to get his car home. I called a machinist friend of mine and Gord took the brackets to Carl and apparently, they were salvageble. Carl is a good welder and if anyone can glue those pieces back together, he can. I haven't heard back so I am assuming that things went OK and the brackets are fixed. If not, there is a set here as I said, that Gord is welcome to use.
