Spiral lox issue - 07/11/16 05:48 AM

SB KB 372 hyper pistons. what spiro loks do I need? I found some loose ones (CS25 on pkg) that when held up sideways are (2) layers thick & they seem to fit OK. I have a full set of ones that are (3) layers thick & appear to be much larger OD & will not fit. I want to go together tomorrow & not sue how long it will take me to find a partial or full set of the (2) layer ones. Can I use snap rings or are these needed? (full floater pins). Any ideas on where to get these? thank you for your time
