If you don't mind deviating from the stock firewall, you could employ a plastic mount. Cox International may have them still, as should EX Model Engines (and I bet Mecoa too). Also quite easy to find on the 'Bay. It would have a slot between flanges that straddles your fuselage, and a plastic firewall. They are usually molded to take a Babe Bee or horseshoe backplate product engine.
I only show this as another avenue to consider. If you slot the fuselage (or drill one hole oversize), you get the added benefit of being able to adjust your up/down thrust by simply loosening screws and pivoting the mount.
