I thought I remembered when Harry put the 5 speed in mine, the inside of the case had to be cut down. I guess I will have to find the hop up notes that I still have to be sure. My mind is not what it was back then and that was a few years ago.. This was the racing 5 speed as there were no 5 speed Ho...

The 5 speed will not fit with out some work. But it can be made to fit.
