Truth part # 41011 and 41012

A quick learner from Charlotte NC says:
I need these parts. The crank handles I have are still good. Can you point me in the right direction? The internal gears in the ones I have are stripped.

Thanks for posting. It appears you have either the 39-253LB and 39-253RB, or the 39-438B and 39-439B operators. The difference between these two sets is explained in the video below--please watch it. In either case though you can use the 39-375 and 39-376 or the 39-451 and 39-452 for new covers and handles, depending on the style you prefer.
