Cut mine out today. Did the first side with an abrasive cut-off wheel. After I saw how much room was inside there I just used a sawzall to cut the second side. That went really fast.
Started welding mine up yesterday. I did the shelby drop and made my cut right at the top of where the old UCA holes are.
