Ofna Center diff question
 

Right about two years ago, I bought a Kyosho Twinforce owned by Promod. The mods he did to it were New era chassis and a center diff, the center diff is mounted directly to the middle skid plate. I want to replace the plate over bulk setup he did, with an RC Monster purpose built bulk, But not sure what i have. I do not have good pics of the diff to really show what it is, The diff is an early ofna with a plastic 51 tooth spur, I believe this is the old LX/Pirate/Dominator setup. I am planning to rebuild the whole truck for light bashing and would like to add the motor mount to the setup.
