What size is hole in center of front rim

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?

Sounds like you are trying to put a modern front wheel drive 100mm wheel on the car.

Again, the diameter for the hub for drum brakes and the Kelsey Hayes disc brakes are the same. The 10 drums hubs even share the same bearings and grease seals as the KH disc brakes.

I have both of these cars that have both brake set ups and switch wheels back and forth.
