Johnny joints are pretty bullet proof, but if you expect to ever rebuild them, get the tools. Makes the job so much easier. I got a full set of Curries used and rebuilt the Johnny joints. It was easy with the right tools, royal PITA without.
That being said, I wouldn't hesitate to run Duroflex either. Your factory bushings are rubber and they last a LONG time.
