I found some well priced very good fittings on Amazon or Ebay, have to check to be sure, it would save considerable funds over name brand ones. I have used Speedway and Summit fittings and hoses before as well, good stuff, reasonable prices.
Used Setrabs are great, do an extra flush with some solvent to ensure no engine bits in it, the fittings are sometimes different as well and look for one with them on the same end. The one I have are verticle, after I installed it I found one with them on the very end, horizontal, even better!
Pretty sure it is Mocal but might be Setrab has a fitting to replace the part that holds the stock cooler on which for a decent price.
I did not find anything when I did mine but found a brass fitting at a small hardware store than worked though I have not been able to find another one like it and looked at different places.
Until I found the part so I could remove the stock cooler I just disconnected and routed around it. There is a way to flip the dual hose connection on the front of the engine to shorted the hose considerably, saves a bit more weight, I am always looking for every once I can remove and it adds up considerably if you do all you can
Hope this helps, DIY is in my blood, love to help others out doing the same
