Inside markings look to be D-186,202 US 1963 on the left side and 11500-4 1-LH on the right. Any assistance finding a replacement would be greatly appreciated

Take a look at our 39-193 and 39-194 Awning Operators. Go over all the dimensions and see if you think this set could work for you. Let us know if the dimensions differ in any way.
