torque convertor

On the Ring Gear, Yes once again like to Repair things.

I agree with all the guys above that welding in the broken tooth is a great fix, have done this numerous times with great success. Have also welded in stripped/missing teeth on manual crank window regulators that fixed them too.

The real trick other than being a good welder and having the welder heat and wire speed set right, is to make a template of the good teeth so that you can use it as a guide to grind the welded teeth back to original size.

Can easily make the ring gear tooth template with a thin piece of cardboard like a cereal box, tape it onto a quarter section of the good ring gear and then tap on it with a large face body hammer to get your template impression.

Here are 2 photos of a successfully welded ring gear on the mopar 360/727 converter. It actually had teeth chewed out in 2 different areas, see if you can tell where the repairs were done.

Now the converter is back in the vehicle and working great as expected.

Good Luck on building your A Body, nothing wrong with saving some money too so you can buy other much needed mopar parts . . .
