started tearing down a 235 stovebolt. got the 3 speed trans off and the throw out bearing. i need help on getting the bell housing off. there are two bolts on the outside at the top and two bolts on the inside near the top. i read that you need to take out the pressure plate and clutch disc before you can get this specific bell housing off the back of the motor. is this correct? this bell housing isnt like the 60's standards or a v8 bell housing. detailed direction would be great. thanks
