The manual doesn't answer what I was asking, it just says to bolt the motor box to the firewall. The previous owner of this plane plugged the mounting holes in the firewall and then drilled new holes for a Saito 90 twin glow engine. I need to re-drill the original holes but since the firewall has been painted, I can't see the spots to drill. I need to get the motor box in the correct location so the prop shaft lines up with the cowl.
I can always try calling Sig.
