Modification on my transmission oil cooler don/t seem to ever end. Decided to shorten the cooler, so i could mount it higher up and out of the way. Had to cut off about 1.5" of the aluminum extrusion. This was a bit of a challenge to mount this extrusion. Eventually I used an expandale arbor on one side and a center on the other and very carefully removed the material. Worked out good with a nice finish on the sealing surface.
