I just got a hi-steer system from rockbuggiesupply.com to fit my 78 FJ40 with 78 knuckles. Everything went well with steering arm installs, cut tie rods to fit and welded inserts. Previous owner installed power steering that uses STOCK setup. For ex. pitman arm, steering box. He said he got the pump off an early toy pickup. Here is problem..... Stock pitman arm needs to be drilled out (tapered) to fit my new tie rod ends. And I'm afraid there is not enough meat on the arm to drill it out to where it needs to be. Any ideas??? FYI I am a newbie at this stuff.
