My buddy has a 2004 GT3 and the shop looked into the parts required and it is 1000.00 for the parts required.,,,if you have any interest I would reduce cost by 450.00 include freight if they do not sell in the morning to the other interested party. This guy has a 996 TT but is changing out the uprights.
If you want the parts list send me an email
grady@willinghamco.com
Thanks,,
