Further update on the steering rack. My car is a 1998 GTWC, chassis #13. Brandon from PAD said the part number was an A1 Cardone part #22-207 and after buying it locally it was the correct part. It is a 1989 Mustang part number. Only modification I had to make was to shorten each shaft by 1.25" on each side so as to screw the tie rod ends far enough to match the original length. However, the main bushings on my Panoz are some sort of Delrin and I cracked them getting them off. I have a call to Brandon to see what they originally used but I am guessing it is some aftermarket part from White Side or something similar.
