SEville 4.1L Oil Cooler Lines-Help!

These seem to have been discontinued, can't find them anywhere.  One of mine has rusted through and is leaking too much to drive the car.  I need to get these replaced.  Does anyone know the threads on the Filter adaptor side and radiator side?  Car is at the dealer and I don't have access to it.  I wonder if I can use Metal Braided rubber hose with a couple of adaptors?

Pkared:  You could probably jury rig some adapters etc and make it work. You could also just buy the right size steel line, a tubing bender,a flaring tool and use your  original fittings to make a new line. It will take you  bit of time but when the parts aren't available we must improvise. Good luck........................

I found some other passages that mention Truck repair shops often fabricate lines and can certainly handle this-we'll see.  The problem is the lines(As you may know) start out with steel tubing ,(Why it rusted through)a nice flared end with threaded fitting at one diameter, switch to Rubber Tubing that is fastened the way they do Air Cond. Hoses, and then it goes to a larger diameter steel tube with flared end and threaded fitting. That's a lot of jury-rigging when there's high pressure involved-

 There's also a place online that has all the stuff to do it :www.discounthydraullichose.com  But I wouldn't want to purchase all the tubes for just one job ig I can avoid it.  That would be a $500 Coolant line.  It is a cadillac though...
