JRSully,
I posted a reply over and the Nova site, but for the rest of you here is some info. The 70 Nova round non bowtie mirror used a snap ring to hold the glass in. Later years switched to the glue in mirror. The Bowtie mirror is reproduced with the snap ring. I do not think that the Bowtiew round mirror is reproduced with the snap ring. I can get them made though.
