guysand gals,i want to install a292 in my 55 panal.so far I have been unable to find motor mounts.ist question would it be possible to used the mounts like the 216 that was in it before?there is four 3/8 threaded holes on the front.give me some ideas please.also the 292 is 3-4 inchs longer than the216.which means I will haved to cut a notch for the damper.would this weaken the front cross member? thanks again.
