The oil cooler is a Fluidyne fluid cooler part number 30617. I got the sandwich adapter from a bender in here that sells the cooler setup as a kit. I don't recall the name of the vender. It is opened up on the inside for better flow. I got the lines made here at a local hydrolic hose shop. Thank you for the comments I hope I helped out some.
I followed your thread on and off and recently scrolled through the entire thing, unless I missed it could you post up or pm some specs of your oil cooler setup. What brand and where did you get the sandwich plate and cooler, also what brand of lines are those as well they look beefy and really nice.
