Amer. Pwrtrain Hyd. Throwout Bearing

I put one in my 47 desoto. I too had issues with the throw out bearing clearance. I believe I cut a piece of exhaust pipe to get the proper clearance. Also the stud that keeps the bearing from spinning was not long enough. I has to weld a bolt on it/ grind it down to make it longer. It’s been in the car for three years without any problems. It’s a 318/833od. I had to fabricate just about everything on the car and this was no different. It has pedals from a ram 50 with a reinforced firewall
