Bought a set of used FIC 650s from a member here but I can't figure out which seals to buy. One of them has "EVO" scribbed on the side. The new ones are a little longer than stock, but several places sell seal sets that they "say" are used for both. I test fit them using the stock seals, but the spacer below the top o-ring is too tall, OR the bottom seal is wrong, because the spacer is getting crushed before the rail is tightened down.
Does the bottom seal sit in the first groove or just above it? Here's pics of the two side-by-side. I searched around here but couldn't find a concensus on which seals to use.
