Measures for diff mount bushing?

[Mr. Horsepower]

Need to make my own diff bushing, but I don't have time to take off the diff to measure the bushing. So I was wondering if someone had a drawing or the measurements for a bushing?

Going to make it in Nylon. Do I need a steel tube inside where the bolt goes through?

I have Powerflex now, and that did not last at all. I can use the holster for the bolt from the Powerflex maybe.

Thanks
