Ethan, the model 100 does not have quick attach, they are bolted on. But my subframe is made for either on a narrow frame. This subframe would go right into any NF quick attach. I don't suggest doing exactly what was done on the other subframe. You would be better off reversing the pins and rewelding them. Think about how having a loose pin/bolt for lateral movement will affect the quick attach latch. Even though that threaded rod isn't great, it won't allow lateral twist as your using the blade.
