    The trans stays, but since its a 97 you will also need to keep the vacuum line setup for it.

    If you have a 97 GT best bet is to sell it for a 98+ car that is already supercharged. Or get a complete wire harness, pcm, engine and trans out of a 97 GTP.

    I had a top swapped '97 GT, ran damn good, would bark the tires into 2nd at 50. Keep the fluid fresh, stay on street tires, and don't drive it like a complete idiot and you'll be fine.

    I have an entire SC top end sitting in my garage. Willing to sell. Includes the lim, SC, pullies, balancer, heads, valve covers. Ready to bolt on (could clean the parts). Came off a running driving car
