Hi, I am at the tail end of finishing my diesel sami conversion. It consist of a rust free 87 body (por-15 underside), 1.6 vw diesel (built by jack), rockyroad conversion kit, calmini 3.5, power steering, 31" mudders, rebuilt tranny & x-fer case, rear discs, rebuilt axles, etc... I have seem to misplaced my shims for my king pins. How important are the shims? I have looked through old thread and write-ups and all I can find is "don't loose them" but nothing on "if you loose them." Any help is appriciated!
