Does anyone have a convenient cross-walk between CBG FIPS and CBSA?

Does anyone have a convenient cross-walk between CBG FIPS and CBSA?

I only see this indirectly on HUD USPS ZIP Code Crosswalk Files | HUD USER

e.g., by mapping both via zipcode, which seems messier than needed

It seems like there should be a more direct crosswalk available.

I’ve used the crosswalk from here before: https://data.nber.org/data/cbsa-msa-fips-ssa-county-crosswalk.html

It goes between County FIPS and CBSA, and the first 5 digits of a CBG FIPS is the County FIPS, so should be more direct.

Second NBER, plus this pretty amazing tool that crosswalks dozens of geographic units http://mcdc.missouri.edu/applications/geocorr.html
