It's not a job you will want to do twice.. Buy a good quality or genuine joint either easy fitted to a fulcrum or take it to an engineering place, I had mine pressed out and new in for a tenner and it's way worth getting it done for you!
I wouldn't use poly bushes ever again, I've had ****part and bearmach ones none of which made the car handle as well as original rubber ones!
Unless you genuinely need extra articulation for extreme use stay with stock bushes they last for years and you won't be swearing at rusted in bolts in years to come...
