That may be right but the beam width of the Head frames are thicker (19mm vs 21mm). So I guess the CAP grommets wouldn't fit the PK BA98.
Ok yeah i suppose it doesnt work then, funny about the headsizes though, that PK also calls there 95 a 98. I wonder if there mid 93 is also an 89,5....Something tells me they must have been looking quite a bit at the head frames....
