There is other methods of removal not mentioned. There is special extractors for stripped out allen head bolts, square ended or some other type of Ezie outs might have worked.

Some people have pounded in Torx type bits into allen had bolts and that got them out.

I was really sure what I did would work and that I could reuse the Bolts if I did it that way. I mean my Striker is back on the Car right now and I did not have to buy or order new Bolts. Nor did I have to drive anywhere looking for substitutes. However, I may look tomorrow.
