68 c30 how do I remove the rear, greasable, shackle bolts?

I've let it soak in pb blaster, used a torch, and a bfh. Won't budge.

Thin cutting wheel on a mini-grinder between hanger and shackle. It's tight and I have ended up cutting into the hanger a bit, then welded up. I have tried a sawzall with the best blades out there and let me tell you, don't even bother. Those are some hardass bolts!

Also, if you have a cutting torch setup you can heat the heck out of it and try turning the end of the shackle bolt thats sticking out with a pipe wrench..

Originally to take it out was that one Allen pin and bump it out? Might just have to cut it out and use grade 10 bolts

Metric grade 10.9 or your sae grade 8 are equivalent http://www.tessco.com/yts/customerse...bolt_grade.pdf

I have only heard of grade 2,5 and 8 bolts unless you are talking aircraft grade or something like that, grade 8 is all you need.....do you know how to tell the different grades?
