Good luck with that.I've looked for quite a while for a pair for my 1990(2 swiped in my yard) and they appear to have been out of stock everywhere for years..They do protect the axle nuts on the front AWD from rust and water so they are necessary.I've thought about maybe making some "cap" on an old metal lathe I have..or a suitable replacement.More than likely that may not ever happen(too busy)..
Since you have one cap..You can use that as a pattern to have someone make something up(aluminium or plastic).The "bowtie" in the middle is a separate plastic plate you might be able to find or something close that might silicone on there.

I'm not running those wheels at the moment so it's not that important for me to make something up for that at the moment.
If you find some "cap" online that will at least fit the same wheel/hub inside/outside diameter/lock ring depth..let me know here! You would think something exists out there that could at least be siliconed on the rim. OEM is not that important to me at this point. I've got a secondary set of studded tires on those rims I might want to put on the vehicle in a month or two..

Well..I ended up buying both..only because I had a credit card credit of $25+ I could use on the overpriced one..and I no longer need to look for them.. Thanks MB.. They aren't anything near perfect..but they'll do for what I need. I can silicone the one on with the broken tabs..I only need to take it off when the tires need to be changed off the rims.
I'm still interested in looking at the aftermarket 83mm ones..wish I knew if they fit right or not..
