O-320 vs O-360 Dynafocal engine mount

Can someone confirm that the O-320 engine mount is 2" longer than the O-360?, and if so, what are the dimensions from the firewall to the engine mounts for both? The mothership is still returning from the big show.

Anyone????

I believe it is actually the O-235 mount for the RV-9 that is an additional 2" in length. That being said, this mount has been used by some for O-320 installations on RV-7's in conjunction with a lightweight (wood/composite) prop for CG considerations.
