i went through the same thing to add to nancy's list before you even make your parts list is think about what you are going to do with the car! are you going to just drive it around? are you going to street and strip? are you going to be more strip than street? 100% strip? 100% street? those are the things you need to think about first. once you know what you are going to do with the car then you can make your parts list. like for me my chevelle will most likely never see the strip so power is not something i am after for right now. so like ray said suspension was first. I am still finishing up my rear and working my way up to the front of the car. This weekend i hope to have the rear end done and back down on all 4s then work on putting the interior together (wiring and seats) then the front of the car (wiring, brakes, suspension) hope that helps
o and you can do like i did make a parts list on the forum of the things you would want and everyone can chime in and help you with things you think you need
