Hubcap question

[darush01]

I have a hubcap i found in our garage off of an 8 lug chevy, it looks like the dog dish caps on my 72 c20 but its chrome and the bowtie is yellow, im thinking its from a mid 70s? But im not sure any ideas id like to know what im looking for to try and find 3 more because they look good on my truck with the wheels painted the grey like the old corvette rallys and a good beauty ring , i have a pic just need to figure out how to upload
