ive recently done this mod to my k1 (cheaper than buying more brca saddles).
parts used:
kf lower diff mounts
db01 belt
cougar sv front axle (used as a tensioner shaft)
kf tensioner would have worked but didnt have a spare one.
rc10 front wheels flange bearings (for tensioner)
these are a smaller diameter than the std ones and allows the belt to be level between tensioners, allowing the shorty to placed better for weight distribution. (i had it forward)
some shims
no dremaling needed.
raced at robinhood raceway last sunday and was awesome
