Default Flywheel Crank bolt circle pattern?

I am wondering if anyone has a drawing or knows the exact dimensions of the EJ series flywheel/crank bolt pattern? I don't have any old flywheels handy at the moment and I certainly don't want to pull an engine to find out. I am looking to make a flywheel adapter for an engine swap that I am considering

Thanks!

i have a spacer from an auto EJ trans, it's about 1/16" thick, but would work as a template.

PM me if interested. will ship it for $3 to cover cost of shiping.
