my guess would be all of the A2s rely on a ziptie at this point, these are notorious for breaking from when i've seen, plastic fatigue i guess as the 5 or so i've seen all break at the bend... Zip tie with a bit of hose where it touches oil pan works fine though.
Would be an idea to make something out of stamped aluminium or stainless to replace the plastic bracket, would be nice, however i doubt many other than most enthused enthusiasts would spend the 30-40quid each (i'd guesstimate) to make it worth someone to make these.
