Hent, thanks for the reply. I emailed Frank a couple of times (quite a while back) with regard to getting these fork tubes in a longer length, but never got a response. Consequently, I can't speak to whether or not these are old stock or of limited supply. Perhaps you, or someone more closely associated with him, would have better luck with that inquiry. Either way, I can't help but feel this item could prove to be quite popular......as anybody who's attempted making these could probably confirm.
