Any have the Hazlet open sockets?
 

I have new Bilstein HD install coming up and I'm reading all the horror stories on Rennlist about those who stripped thing by not dropping the $100 for a set of three sockets. These are the sockets with the chunk cut out of the side, through which a hex key goes to hold the strut bolt in place while tightening the nut around it. No way am I spending that cash on a tool I'll use once. Impact gun is possibility, but a bit risky too. Anyone? Thanks.
