I thought about extending the motorbox and not using an engine spacer. But, my flying buddy has a 4 cylinder that he thinks would be fun to try on this plane (after I get a few flights on the plane with the twin). So, I started in on an engine spacer. This is the longest one I've made... 2-3/4". Here is twelve pieces of 1/4" aircraft plywood rough cut. I actually only need eleven so one will get tossed. I still have to lightening hole them all and drill the four bolt holes in all of them. Then I'll epoxy them together, grind that hunk down with a drum sander, and finally seal it.
These 4-1/4" long bolts are not going to be long enough to get a locknut on the other side of the firewall. I'll need to order some 4-3/4" bolts.
