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 t= he 13B plate to the 20B/RX-8 plate, then yes, definitely torqued. =A0They w= ould need spacers so they would bolt solid and there wouldn't be any sp= ringiness. =A0

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