Difference between 2pc and 1 pc RMS Flywheels!!

What is the easiest way to tell if the flywheel I got with my T-5 swap is for 1 pc rear main or 2pc?
Thanks
Steve

According to number on my flywheel
Hays Billet...10-330..I figure thats for a 2 piece Rear
So I bought a new flywheel for 1 pc
10-530
2pc rear Flwheel is for sale if anyone is interested

bolt pattern is different for one

one side of the plate will have pattern of the crank flange on it

if thats perfectly round then its 86-up

if its all big and irregular then its 55-85 years

1-piece RMS flywheels are counterweighted. 2-piece aren't.

not only what was tpyed already, but a 1 peice flywheel will have a tighter bolt pattern...wereas a 2 piece will have more radius from the crank centerline to the bolt holes.
