A few of the aft 3/32" holes were a little egg shaped so I opened them up to 1/8" by installing the cooling ramp with clecos and then drilled the holes up. Uninstalled, deburred all sides and then dimpled to 1/8". That's all for now as Holden is home from college and the Rangers and the Longhorns are on the diamond - at the same time...maximum viewing potential!
