To use of not to use? Need answer soon please

I am in the middle of installing my southbend single mass flywheel conversion on my 1995 F-250 and I just got the transmission mated back to the block.

I didn't use that washer ring (metal ring between flywheel bolts and flywheel) that was used on the stock flywheel and was wondering if that is the correct way to install the new flywheel? I just want to make sure I installed it right before buttoning up the install any further.

Please help as I was hoping to finish the install today. Thanks!
