If you decide not to watch the video I made make sure you be really carefull when you tighten the "perimeter" bolts to do it by hand and not much more than finger tight. I had to do mine twice and two of the threaded inserts came loose after I tightened them the first time and I barely tighted them at all. Pain in the ass to cut the heads off the bolts and tig weld the inserts back in place. I was lucky to have everything handy to repair the inserts.
