please o/s ripper owners, ive lost the dimensions for the slot/hole on the top of the seat post tube.
im machining one now (waiting for the sizes

)
for a member on here who ive promised i will try to post 2morow.
the 3mm wide slot runs into a 6mm diameter hole, i need the overall dimension please from top of seat post tube to farthest part of hole. i think its about 28mm but could do with checking first.
