My last remaining fluid change for my new-to-me C5 is the differential fluid. I went to my local Chev dealer today to get a set of crush washers for both the drain and the fill plugs to have on hand before I start.

Their exploded views do not list any part #'s for either, even though they are both shown and numbered.

Any thoughts? I'm guessing that I'm not the only guy to ever want to replace them. Anyone have a source? Or maybe just a size so I can use something else??

Thanks in advance,
Tom.

Its a 20mm crush washer. The local parts store have them sometimes but are hard to come by. You can get them from Amazon or eBay. Also in a pinch, reuse the old ones and check for leaks after taking it for a spin.

Ive never replaced mine. Never leaks.

Thank you both. I've reused similar washers and have never had a leak. But I'm the guy who would always like to have an extra hanging around than to need it and not be able to find it.

Off to find a couple.

Thanks again.
