My vision is similiar to yours and it's almost complete(this summer).It sounds and looks like you are going for the JDM/Old School Z look. Ebay can be your best bet to achieve this and remember that most of the time it is the little stuff that really makes the car. Be sure to plan everything out, make a list, and each time something on the list is done check it off. Its pretty much never ending and you can add/remove items as you please. You will be amazed at how this will simplify the process. If you get the side stripes im not so sure the fairlady emblems would be appropriate. It is kind of a mismatch, but its your car so it is your choice. Old school style wheels are a must. Watanabes, SSR, Advan, etc. Wheel importers can be found all over the net. As Scott said, "Louvers are VERY old school." Most definetly true. Dont forget about the interior either, unless you want to leave it be.
