Help stripped shock shaft hex

[naossoan]

Hi all,

I previously lowered my yaris with some tein springs but I have moved to a new location and needed to raise the car back up to stock height for various reasons.

While working on the front struts, I managed to get the passenger side strut out from the car, but while attempting to loosen the nut which actually holds that top piece on the strut, the top hex thing stripped out.

It wasn't in the best condition from the last time I did the job, because if I recall correctly I didn't exactly have the right tools.

Anyway, now the top hex part that is needed to stop the shaft from turning while loosening/tightening that not us stripped out and I'm not sure what to do at this point.

I was considering taking a dremel and grinding a slot into the top of the shaft so I can put something in there, but it's gonna bugger the threads and be really difficult to get the nut off/on again.

Any better suggestions?

Oh and the driver side 19mm bolts that hold the strut to the lower control arm or whatever are crazy tight. I can't get the same strength on them as I could on the other side since to loosen them I have to pull down, whereas the other side was up so I could put a lot of back into it....any suggestions for loosening those buggers?
