What I did, was cut the original hard-line about 3" from where they screw into the oil filter housing. (This end of the line usually comes right off) Then, weld on a 1/2" MIP to 3/8" FIP steel reducer. These are available at Home Depot for or any plumbing supplier for about a dollar.
Any welding place can weld these on for you if need be. The factory steel tubing is thick, so it's easy to weld. Then, add a brass 1/2" barbed x 1/2" FIP hose fitting (again, Home Depot). The last step is to get an aftermarket oil cooler with some BIG lines, and run your hoses to the front. I found a very nice cooler with specs similar to the Benz cooler on eBay for $35.
Here's what they look like when ready to add hose. I didn't want to take them off again for the photo. I chose to run my hoses up beside the inner fender. You can point your hoses in any direction you choose. Total cost with new hoses and clamps....about $60. And, ALL your parts are now new, not repaired.
Hope this helps.
