Is it possible to leave the stock oil cooler in place but replace the leaking oil cooler lines with 'home made' lines? I'm thinking of taking some fittings to the hydraulic shop and having them make some lines, then just mount as necessary.

Yes I did just that on mine. The trick is adapting across to the thread on the oil cooler which is a straight thread. Now I could of sworn that I read somewhere that in addition to the early lines being 1/2" diameter the cooler threads were also different to the later 5/8" diameter lines.
I am fairly certain though being a 97 that yours will be the same as mine a metric straight thread of the size M27 x 2.0. You can get fittings from Parker that come with a straight thread on one side with a Viton O-Ring to seal and the style of fitting you choose on the other.

The fitting that I used converted from the M27 x 2.0 to a 1/2" female NPT Parker part# 222P-8-M127, this will be in brass.

Because of the 5/8" hose you should be using 5/8" SAE -10 flare fittings and parker does not make a direct crossover from the M27 x 2.0 to a -10 male that I know off which is why I used the above fitting.
I recommend that you use a 45 DEG fitting to adapt from the NPT to a -10 male flare.
I also plan on putting in a bypass filter on mine so on one side I installed a T for this, I can take a picture tomorrow if you like

cheers

Nice kit! Reasonable price. But for me not yet installed. The oil cooler is a Long (made in Canada) and the lines SS braided which is great.

Sure you could do a custom setup but what is your time worth running all over town getting lines fabricated? And still probably paying about the same in the end.

My local hydraulic shop wanted $130 for just the lines before doing any special fittings. For $225 and piece of mind I went with Greg's kit. I was also under a deadline since my truck has been down for such a long time so I didn't get a chance to shop around alot for lines and fittings.

Good luck.
