This is just the latest one to leave the shop.
It has working a/c all factory gauges, speedo and tach are correct stock gas tank with the stock fuel pump and filter, and if you didnt lift the hood you would never know the car isnt stock. (That is until you hit the go pedal)
I am not trying to down you but you are really not approaching this swap in the correct direction. If you want it to look and work like factory it is gonna cost some $$ in parts and labor as well (spent correctly of course). I have already re-wired two swap cars that "experts" adapted the factory 4th gen harness to work in the third gen car.. they were fire hazards to say the least..
Budget is not about spending as little as possible, its about spending the right money in the right places.
