I have a LRP fusion I bought second hand which is duff. Luckily I have been refunded the money and was told I could probably salvage the endbell and armature as the magnets had moved in the can. The armature is a 12x2. I was wondering if i could run it in a 19t can and get similair performance or are the cans much difference. I know the armature and endbell fit but are the magnets weaker etc?
