i think hes talking about a 110, nobodoy makes hydrolic clutches for 50s. im pretty sure they are all cable drawn
but to answer your question, the TB clutch kit is hands down the best for under 200. for a little closer to 200 you can get the takegawa manual clutch kit like TBs, i think its like 190 or maybe 200 for the tak kit and 170 for the TB
