Hi Ron,

  It turns out Summit had the right adapter for the kit, the sales 
person just didn't know it. They have sent the adapter to me and it fits 
correctly in the block as well as in the kit. The only problem was the 
oil filter they sent me was incorrect - it hits up against the oil pan. 
Is it the ph3600 that is slimmer and fits that kit?
  I also found another problem - the oil line from the oil pressure 
gauge was cracked and leaking. when I disconnected the oil line fitting, 
I also took off the fitting that goes into the block. It was very 
difficult to get off and I am concerned that someone either put a 
fitting in there with the wrong threads or stripped the threads when 
they installed it. Do you know what size those threads are? It appears 
to be a british standard pipe thread. I had to use whitworth wrenches to 
get both the pressure fitting nut and the fitting to the block off. Any 
info on these fittings would be much appreciated.

Cheers, Terry
