so datman ur sleeve isn't an aluminium one. i worked the other way round. i welded a push fit engineered pipe to the diff and slided the sleeve into it.

on the next b310 we r going to work on a new system. we r going to work an s13 top plate where the shock is and reinforce that part and then use s13 shocks. i'll post photos while the job is being done since till now i am gathering all the parts.
