so!.. quick update .. I checked the crank shaft just in-case it was faulty bearing, but nope.. without that 3rd tab, the plate doesn't seem to secure properly into the shaft.. even when doing up tight

I did the bolt up extra tight, and seemed to reduce the movement.. but.. after running the mower for a couple minutes and shutting down.. I noticed the blade-carrier took long to stop.. removed the carrier and noticed the last 2 tabs goooone...
So! .. I guess my option are now,
1- Replace carrier + Boss (just carrier if I can find one the same style.. not holding breath)
2- Weld (or get someone to weld) mew, thicker, stronger tabs..
3- Try sell as is at reduced price.. someone else can havce a go and fixing the carrier or buy replacement...
Think I'm gonna go fishing with #3, see if I get any bites...
