Hm...I drove my friend John's once, and it sucked with steering. SO, at least a 645 is in order. What else... Mabye lay-down servo tray? Get a different pipe, his has a hideous tone to it. Some aluminum clutch shoes are also a must, we've probably gone through 3 sets on his. Anything else....Lemme think...Get a clear body and paint it up nice. The stock body is hideous.
