I’m pretty good at everything I try to take on. I have been building motors, 4 speeds, restoring six packs, etc. I try to garner all the information I can get to get started. My transmission man has told me a lot through the years. If he’d just do the job, I’d let him. I can do it. Just rather let him. In my casual conversation with a Mopar friend, he stated he thought they were easier to build than a 4 speed.
