Yes, spacers will be required, approximately .250&qu= ot; 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 disassembled if necessary.

Mark,

=A0=A0=A0Do the bolt points of both flexplates nest together without any space between = both

flexplates or will spacers be needed when bolting together ??............Could not tel= l

All,

Attached is a picture of my proposed solution to the cracking flexplates. =A0I used my ol= d 13B flexplate, removed the ring gear, and nested it inside the 20B/RX-8 flexplate. =A0It could be held together by bolting or by welding around the outer perimeter, similar to how the ring gear is attached, although welding= may cause warping. =A0If bolted, there would be ten bolts holding the two flexplates together. =A0I favor the bolting method as the four bolts holdin= g the aluminum adapter will be a bit tricky to install and bolting would make= it a bit easier to assemble. =A0
