When I get to the point of completing mini truck knuckle conversion and to stage of selecting shims to set steering arm preload, I may or may not yet purchased new 4x4 high high steer kit (which I will eventually). Question: Will I be able to set correct preload and test with fish scale with my old stock 40 steering arms if I drill them out sufficiently for the larger mini knuckle studs and just use flat washers to temporarily determine if I have selected the correct top shims? I'd like to use the old arms during this part of the rebuild, then buy the high steer kit later on during the rebuild. Just trying to spread out some of the expensive purchases. Thanks.
