Roller for 50 yr old door

We have a few different rollers in this style, but I'm not sure exactly what to recommend. Before we go any further, I'll need more information.

First, can you show me a photo of this roller from a side angle? That will allow me to see the rest of the housing. 

Can you also give me detailed dimensions? I'll need to know the height of the back end of the housing, as well as the total width, including the tabs on the side, and the width that does not include the tabs.

Thanks for getting back to us! This looks the most like our 81-057, however it differs in a few key dimensions. Namely the height, which is 1-3/8" on ours instead of your 1-3/16". This part also has a different total width from tab-to-tab at 7/8" compared to your 15/16".

I recommend triple checking your dimensions just to be 100% sure. So far, the 81-057 looks like our best bet aside from those two differences. Looking at your last photo, your height looks like it's smaller than 1-3/8", so definitely check that.
