You would need tapered washers to make that work.

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

Yes, spacers will be required, approximately .250" thick, unless I = decide to connect the two plates via welding, then it won't matter if t= hey touch or not. =A0Originally, I thought they would nest together without= the need for spacers. =A0I like the idea of bolting them so it can be disa= ssembled if necessary.
