As most of you know the 22m bolt on the bottom of the s/c loosens easily. Over time from coming loose and threading it back on the threads have gotten trashed in the aluminum egr block Tad had custom made. The machine shop told me they would probably not be able to helicoil it for some reason (non standard threading or size or something). My questions are:

1) If I find a stock egr mount will it work?
2) Do I need to order a S/C egr mount from Alpine/Tone?
3) Tad if you read this, do you know if the 22m hole was helicoiled and if so, a helicoil part number or something?

As usual, Thanks in advance
