Topic: 1967-8 LH reproduction remote/RH manual. Mounting issues?

[1967 eight barrel]

I recently purchase a set of high quality reproduction mirrors. The base is just a hair off the rivnut spacing on both doors. The LH is as it was and the factory base sits on with no issue, but the repo doesn't. This is the case for both. Has anyone else had this issue with repos?
