Did you put the cross hairs on the firewall extension, or were they marked by the kit or ARF's manufacturer? Normally marks such as these indicate the port/starboard/up/down location of the thrust line, which is what your asking about. If these marks are correctly positioned, this is a centerline you want to continue through to the center of the thrust washer of the engine.
I'd like to help you but I don't have enough information! Is there right or down thrust? Who manufactured this aircraft?
Maybe someone with specific information on this Cap 232 can chime in with the specific information you need.
