What size is hole in center of front rim

The bore is about 2.3" on the small bolt pattern wheel. Couldn't get my calipers on square that's why I say about.

I have a rim that wouldn't fit and it was 2.3" so it must be larger. It has the Kelsey Hayes front disc brake set up so it is larger than drums. Unfortunately the car in in for paint and I cannot access it to measure the front hub.

Maybe it is 2.85"

Anyone know for sure?
