Thanks Donnie. A picture is worth a thousand words. Those are worthy several thousand words! Looks like the plate that you encounter by poking a rod about 12" up the pipe is that one right on the exit side of the grid plate (A1) and does not have a designation in the pics. Bet that bitch is made from Ti or something harder though. Maybe I can get the shops to weld me up a 1/4" and then a 3/4" bit to some extension rods and make a penetration (uhmmmm, "penetration"..........) .
Hey Byrdman, how did you accomplish the mod and what size opening did you put in?
