You took them to an idiot. Everybody who might rebuild their front end needs to buy a cheap 12ton press ($120 or so at Harbor Freight). The guy pressed the bushing into the LCA first and then without supporting the inner sleeve of the bushing he pressed the pin in and too far. I can show tricks on the upper bushings because it is easy to hurt the upper control arm if you aren't careful pressing the bushings in and out.
