If you insist on doing this, do one crossmember at a time and make a steel jig to keep things square. I recently re-riveted the rear engine crossmember and made a procedure for it. It's here..

I do not recommend using bolts because they serve a different purpose. Has to do with physics and engineering shear strengths, etc. Grade 8 bolts WILL work, but its not the best.
