Tuning Impact hammer spring spacer dimensions?

Since the .30 M3 doesn't need any part of the FX slug power kit besides the hammer spring spacer/weights, it seems like a waste to order the entire kit just to get those two spacers. I want to see if I can source something from McMaster on my next order, but my searches for the dimensions of these spacers have come up empty.

Can anyone help with this info?
