This topic picks up on a mini-conversation that I started on Grannyknot's 280Z build thread. These little washers are an important part of the NVH isolation design for the Z's rear diff. The design, from an engineering perspective, is a lot more sophisticated than meets the eye, so there's an incentive to try to install a proper replacement if your own have deteriorated (which they probably have, if they're 50-year-old originals). Unfortunately, the part is NLA from Nissan and none of the primary Z restoration parts suppliers offer a substitute. There's been some discussion about the need to use vulcanized rubber. I think that's a red herring (look up, 'vulcanized') and was meant to infer that the rubber part needs to be bonded to the metal part. While the originals might have relied on a heat-bonding process, its now 2019 and we have aerospace adhesives for this purpose. So: All we really need is the rubber part. Steve / Nix240 has cobbledup a wide range of rpreviously unavailable rubber parts for our Z's. I see nothing special about re-creating the moustache bar runner washers, other than using a suitable durometer rubber and having access to a good-condition original to create a mold. After that, they could be bonder to a suitable metal washer and, presto, we have another part taken off the NLA list. I think these washers carry across the entire 240-26-280 series without any differences. Maybe even the ZX's? Also: I'm thinking that the same might be the case for the Series 1's diff front insulator. Steve creates the rubber piece, then the owner carves the perished rubber out of his insulator, cleans up the metal armature, and then bonds in the new rubber. @nix240z Steve: What do you think?
