Re: 3sp to auto trans?

No need to change the humps. Ironicly, I am changing mine to a high hump on one of mine because it it going to a 5 speed. No need to do so I just think with the open floor it will help me get everthing the way I want. Plus the other two truck I am building at the same time will have the same humps as they are big blocks. Jim
