Need help with Centerline Wheel

[asbill71]

Was hoping someone has a wide 5 Centerline Wheel easily accessible. I need the size (diameter) of the large center opening. Any help would be greatly appreciated.

Thanks

I'll have one this weekend. If you don't hear from me, it means I forgot. Reply to this message, it will send me an email, and I'll be reminded to get the measurement.
