888 response?

what size response do I get for an 888? (not 888x. slim cbc are too small)
I put in some silicone, but I like pads better.
I think it’s an 08 888. on the inner rim… area it has the 888 and yyf in fancier lettering.
the width of the groove I put silicone in is 4mm, and the diameter of the circle itself is about 22mm.
and it’s an a size bearing

I have an extra pair of the white cbc that say (888 size) from when I bought my g5. they’re too small…
