full floating rod bearings

ok, so have any of you guys n gals got any good tricks on dialling in full float rod bearings first time...??
i gotta do a flattie in the next few days, and i remember that it wasnt much fun last time i did it...
are there any alternatives or tricks you geezers can suggest, to help make this a lil easier?? its a job i abhor anyhoo,and doin it with a busted up hand is gonna be a challenge...lol..so any ideas to make it easier will be worth a shot.

Thanks in advance.

Go steady
Jay
