Where is the cooler leaking? Maybe it can be salvaged.

The AN Stainless hoses would be pretty easy to make up. Here's the list of parts.

2 ea AN 10 weld on fittings - about $5 each
2 ea AN 10 x 1/2 NPT - about $5-7 depending on straight or 90 degree
4 ea AN 10 reusable hose fittings - about $10 ea
3 ' AN 10 stainless hose - about $10/ft (guessing here on length)
Welding (actually brazing) - about $10 each (I used my local A/C shop)

That gets you to about $120 in materials and services. The only other thing that needs to be done is the oil cooler needs to be drilled and tapped. It's a pretty easy process but you need a drill press, a 3/4" step drill and a 1/2NPT tap. That gets you a solution well under the $200 you said you'd be happy to pay.

Everything listed is available on ebay, online speed shops and likely local speed shops as well.

Vstech, is the fitting setup on the 603 cooler essentially the same as the 617 cooler? Do you think the same drill/tap approach would work?
