Skid plate cj7

I did a transmission swap. Went from the factory t5 transmission to a sm465 transmission. Got it in the car with the Dana 300 transfer case. Bought a new transmission mount for it but after putting it up and the skid plate I realized I needed to put a spacer in between the skid plate and the AA adapter to mount it correctly. Do I need to put spacers in between the skid plate and the frame or just the tubular spacer for the mount? Do I use the factory torque arm after the spacer? Lost until Monday when I can call advance adapters...
