I need 2 of the common tear-off type glass for a model 15..

I have two part numbers - 93834 and 120686

Is either number correct, if not what is the correct number?

I also need a toothed belt for a Model 28 Reperf.

The two pulleys are about 4 inches  center to center.

The only number I could find for that is - 161520

But it did not say the length of it.

I already have a belt that is much too small.

I want to be sure I get the correct one.

Thank you in advance for any help.
