I recently picked up a 1981 R80g/s that had 4,600 miles on it. It had been in storage since June of 1990 when the tag expired. As part of it's "sitting around in a warehouse for 22 years" phase of its life, lots of rubber and plastic has dried up.
There have been multiple issues with the speedometer, from the odo button missing to the plastic backing cracking in half and now the speedo needle is stuck at 75mph. Every time one thing gets fixed in relation to the gauge another issue pops up. I was looking for a replacement unit when I came across these replica units out of India on eBay.
I'll report back on how well this looks and works when I get it. A nice touch was that it is calibrated for 120mph versus the 80mph of the OEM cluster. I've had my g/s up around the 80mph mark a couple of times trying to keep up with the flow on I-40 so having the extra room without having to worry about bouncing the needle off the pin at 85 mph will be nice.
Has anyone tried one of these units before? I couldn't find reference to them in any of the usual Airhead forums so I decided to order one and try it out. I don't like that it is a replica but most of the OEM units of that era are either broken or about to be. I do like that the backing is all metal. That alone should make it tougher than OEM.
