Paul, I too already had the 600 delphi gear box. So I ordered the kit without box,but they send a correct mounting plate to position the gear box correct angle and further to front of car.They send a longer intermediate steering shaft also. The new idler arm is put in original holes in frame.Pitman arm is also included in kit,drag link, sway bar and link's tie rods end's.For some reason I had to get longer grade 8 bolt''s to get the sway bar higher to clear over the tie rods adjuster,about a inch longer. I shimmed spacer in the link''s with washer''s for now ,but will replace with longer spacer later. I drilled the hole to get bolt in blind cavity right under the c bracket's in the middle so when c bracket's is bolted up ,that hole is covered up. You must mount gear box with their mounting plate ,otherwise is will not be correct position for drag link and tie rods. If you need better pictures ,I can ,but if you do all as designed it will fall into place ...You will need a notched radiator as I have as you can see the gear box protrude''s under radiator. I will post the kit number I got.
