Not sure which bolts you're referring, there are eight (8) around = the outside perimeter, and another six (6) that bolt the assy. to the e-shaft. =A0If you're referring to the four bolts = that attach the 13B plate to the 20B/RX-8 plate, then yes, definitely torqu= ed. =A0They would need spacers so they would bolt solid and there wouldn= 9;t be any springiness. =A0

The trick will be with the four (4) bolts that attach the = flexplate assy to the aluminum adap= ter. =A0Those bolts will have to be inserted through the 13b plate from the= rear, then the two plates bolted together with the other four bolts, then = the assy bolted to the e-shaft, and finally, the = alum adapter bolted to the flexplate = assy. =A0I am picturing a special wrench that has been heated= and bent to fit in through the lightening holes on the 20b fle= xplate. =A0Its tight, but workable. =A0
