its a real easy swap! just made new frame mounts and used stock f body motor mounts. headers can also be used from a 1998-2004 camaro. little pocketing on the pass frame for clearance. i used a 4l60e and all i did was make my crossmember out of 2x4 box tubing and set it up. do a little trimming on the front core suport and you can use the stock camaro radiatior and fan assembly. stock upper hose works. had to two piece two lowers with a piece of tubing to make it fit. as far as wiring harness save the money and the headaches and get painless wirings new stand alone deal. alot less wires and their computer.
