Here is my jerry-rigging concept; this is for anyone whose seat is too low, stuck and they are needing to raise it to avoid a case of sore knees when riding, and doesnt mind doing things a bit differently.
1. Go find another seat post
2. hack saw it to appropriate length (you'll be sleeving it over the original seat post)
3. sleeve it on over original seat post
4. its going to swivel like a seat post in the tube with no nut to tighten it so you can:
a) try drilling a hole through em both and insert a bolt/nut
b) hammer the post down over the original one where it begins to get bigger.
I guess the seat post might crack on option b, but I opted for that route and it worked great, problem solved!
