Need del mar double rollers for sliding door

A quick learner from Livingston, MT says:
I bought the 81-108, but they did not work on my wooden door from the 80's. They made the door to high to slide back in to it's slot. I'm wondering if your 81-137 might work, as it is described as being a deep mount.

Thanks for writing in. Can you show us pictures of your original roller out of the door? That would help narrow down what you need. The width and height of the assembly, as well as the diameter of the wheel, would also be needed. Many thanks.
