Rear differential brand identification ?

[Turbo67camaro]

Anyone able to tell me what brand of differential this is ?

Attachment 24549

I had this rear built about 12 years ago, and forgot what brand of differential we used (GM, Eaton, Auburn, Richmond, etc.).

My builder thought it looked like a Richmond, but he's more of a Ford 9" guy.

When I get this car done this year, someone is bound to ask what differential unit I used. It would be nice to be able to answer instead of sounding like a dumba$$. Plus, knowing if it was an aftermarket one, might influence if I should ever dare to try slicks on the car.

Thanks,

Mike
