It worked
Well after much reading here and thinking through the process several times, I got out the file and made this conversion work. First was the bottom of the barrel for the stainless cylinder gas ring to clear, then about .030 off the locking pin at the front. Cylinder dropped in and I got lucky with no ratchet cutting. It worked and cycled fine. I will take pictures tomorrow in daylight. Very happy and many thanks to all here who contributed to help me out. Not bad for a $13 stainless cylinder from gunbroker
Have a blessed evening
