i plan to get matt francis or dynamite aluminum suspension parts (arms, blocks/pivots, knuckes, etc.) will they work with each other? even with the stock parts? im on a budget so i might get a pair of arms first, then the blocks/pivots, and so on. also, i saw the dynamite aluminum blocks/pivots with delrin balls (for the hinge pins, i think). are they replaceable? do you guys know the part nos. for those balls? if ever i get the blocks, i might order additional delrin balls. I havent seen the matt francis aluminum pivots yet. do they also have those delrin balls? or do the hinge pins ride directly on them? thanks for any info
