Butter boards were manufactured and distrubuted by Triton Sports (makers of DoubleUp Wakeboards also). Back in...shoot, '03 (?), they also acquired KD Watersports. The LAST known contact info I have for Triton and KD, in the US, are below. The mailing add'y and telephone #'s are the same for Triton and KD. I do NOT know about the email add'y. Maybe they can hook you up if the RedX aren't the correct fins.
