Awning crank operator

A contractor from Beaver County, Pa says:
Hi, Having trouble finding one with all matching measurements. Which would you suggest, even if modification is needed on my end.

In case you can't make out the #'s as follows:
  • Bottom mount holes - 1 3/8"
  • Bottom to top m hole - 5 1/4"
  • Arm extension - 2 1/4" 5/16" hole
Now that 5/16" hole that mounts to the window unit has a pin on it.
I just popped the C clip off

Only marks anywhere including the window is the # 75 on the crank arm.
Nothing else at all and i looked everywhere with a mag glass.

Hope things are clear enough.
Thanks for your help

Thanks for posting, Rob.

Take a look at the 39-194 operator, it looks like it could be a match. However, you said that our arm extension has a 5/16" hole. Looking at your photo it appears there is a nylon bushing in the hole. If this is something you're going to replace, take a look at the 33-206 bushing.

Guess that will work even though not everything is exact specs, should do fine.

Thanks for the input.
