Plural. Thread is about just the dogbone mount. So are you saying you have all 3 VWR mounts, and all 3 have failed? No mention of that in this thread, not that I could find amongst all the bickering at least.
Yep, the blue ones are poly and not made by Vibratechnics.
....My apologies, although I wrote both original review threads it's a few years since I revisited here and I got them mixed up.
Yes, my BHS(?) arm failed and also the 2 VWR engine mounts, not blue poly, failed.
My gearbox stabiliser arm has been replaced with Vibra Technics and the 2 engine mounts with revo.
