the diff circlip... once it pops out the first time, it will keep doing it
i *think* the williams box is the same, for a bolt in circlip you need a 172 box
K4M is a 1.6 16v ( 99 - present day ) engine used in all renaults
Fit a JB3 974 from a Kangoo 1.9D or a JC5 128 from a clio 1.5D ..... 100 will come quicker but 110 wont come at all
Williams do pop the cir clips.I have never heard of a williams box (JC5) popping the circlip so that would probably be a good option as they are the strongest of the mk1 boxes.

LOL - theres no such thing as a JC3 or a JC2 gearbox ladies
