Had to shorten theoil cooler extrusion by about 1 inch to make it fit better between the air frame longerons. Mounting the extrusion on my lathe was a bit of a challenge. I finally founf a way by using an expandable arbor to fit inside the extrusion and using the center on the other side. Got a bice sealing surface for my o-ring this way.
Also made an aluninum billet part to hold the transmission vent line in place
