669 stinger mold

I need your help please. What size C clamps and how many clamps do i need for 669 stinger mold thank you.

2 clamps are fine. Lowes medium clamps are fine

go to the hardware store and get a pair of these are use these 100% of the time when I'm shooting plastics. I'm able to clamp three molds out of time but usually I clamped 2 or single.
