gibson deluxe tuners vs. Grover tuners

[in a vacuum]

I have a Les Paul Studio on the bench that is missing the washer and collar off of two of the Gibson Deluxe tuners. I need to order these parts. The Grover collar and washers look similar if not identical. Are they interchangeable? The Grover stuff is a few dollars cheaper.
Thanks in advance.

Probably the same parts. Gibson doesn't make these parts. Schaller used to make their parts (tuners, bridges etc.) but I wouldn't be surprised if they had more than one source and they used to use Grover. I don't know who makes Grover anymore... but it's not the original company.
