Cheap oil cooler hose replacement.
I ground off the crimped collars off of the oil cooler hoses on my 84 300D with a dermel tool and replaced only the rubber hoses. I cleaned and degreased the hose barbs with brake cleaner, applied silicone sealant to the barbs, slide the hoses on and double clamped them in place.
If someone is interested they can see 6 pics I took at this free pic host site: http://s242.photobucket.com/albums/ff279/Diesel911/
For some reason picture #1 is starts at the bottom.
If someone is interested in a more detailed description let me know.
