So I went and got some bolts..they are threaded all the way down the bolt so I can't run out of thread..still can't tighten them all the way up they just spin, even after I have retapped the subframe nuts with an m10x1.25 hand tap. Wtf? For the moment I have secured the bolt with a second nut on the back of the subframe nut - its tight and definitely not going to come off. Still got nfi why the bolts won't tighten from the front though, both left and right side are the same. Could the subframe nuts just be totally ruined, even though I retapped them?
