ohhhhhhhhhhhhhh.....i like the look of that impact stud extractor 
not seen one of them before,thanks for sharing,helicoils are easy to fit and there`s plenty on the bay,have used several in my older bikes,there like a tightly wound spring that winds into an oversize hole which enables the orignal size bolt to be used....very handy 
, good luck with the re-fit
