Oil Cooler Lines?

[cheryl_ford@bc.sympatico.ca]

hi all:
My 87 5000cstq has a leaky oil line.  The shorter line from the filter 
housing to the oil cooler is sweating on on transition joint from the 
tubing to the braided stainless steel.  I was wondering if anyone knew 
what type of fittings and their sizes these hoses use, as I am hoping 
to have a few lines fabricated.  

While I'm at it, I thought I might as well get replacements made for 
the other hoses in the engine compartment. I was wondering what 
types/sizes of fittings are used on the coolant lines to the turbo, as 
well as the various hydraulic lines...

TIA
