Pinion Nut

I need a pinion nut for a 07 gt 8.8, local parts stores are telling me its a factory part, as well as being on back order.

Is there any other nut from a different rear end i can use?

the pinion nut for the 8.8 is fairly common. Amazon, Summit, etc show them available to purchase. Any local dealer should have them as well really

I'm seeing "389546-S100". Beyond that, it looks like a lot of aftermarket companies are using "33154" as their part number. I found one listing that describes the (flanged) nut as having 3/4"-20 threads.
