maybe they are caps
I was always under the impression Suzuki used KYB exclusively in the early years and never actually physically seeing Showa items on any of mine or others early Suzuki had me make the comment. Been wrong on many occassions and it's quite possible this maybe another one..will look into it a little further
suzuki's definately ran KYB on the rear so to me that also states it'd be Kayaba's up front also.
