Part identification please?

I found these in my parts tub. They look like hub adapters. I got these with my Tecate back in 1988 or so. They look to be a small 3 bolt pattern to a larger 3 bolt pattern. The small holes measure 1.75" center of hole to center of hole. The larger pattern is just a hair under 3.5" center of hole to center of hole. Anybody have any ideas?

The back side has a 3" round marking where they were attached to something. A hub I am guessing. They are .250" thick and look to be cadmium plated (gold color). Here is a pic of the 3" mark.

There are 2 of them so I figured they were 3 wheeler related.

Thanks in advance,

looks like they go to a front wheel hub assembly.

I think they are adapter plates for the us90.To be able to run newer sytle rims.
