oil cooler

I got my oil couplers from a salvage yard so new gaskets were required no doubt... Unknown about the American Classix couplers....

I bought a metric O-ring kit from Harbor Freight Tools... Something like 300 of various sizes.... Your local auto store should also have something that would be close in size....

As for the chain guard... ACE hardware.... :blink: :laugh:

Aluminum angle, cut some curves, braised some 1/4" x 1/2" flat plate securing straps/pieces and buffed her out. Seriously, that's all that is....
