just so you know (I did the lambo hinges,etc.. already) had it on my car done, took it off to make production parts and got too busy, but the shock you need needs to have a force of 600-700 pounds of pressure
trust me, try mcmaster.com look for shocks, its about 70 bucks a piece. Ive got the part number at home, I ll search for it.

these doors are HEAVY.
oh and my tip to help you figure out the hinge design is (swivel bearings)
