ive got over 20K in mine and still have no interior and a rear end that will be questionable at best at the track. If i do it again i will start with the chassis first before i get it running. otherwise you will be pulling it apart time and time again to upgrade drivetrain parts. I would find a relatively rust free shell, connect the frame rails. Install a 10pt + cage. a custom narrowed c-5 vette rear with steel shafts. and a 3 speed glide. then get the electronics and motor stuff installed.
