Thanks for info.I have a set of lift pucks from Cooltech. Make me an offer.
For part numbers the service manual on CD is invaluable if you can find one. If you don't have one (you should) then I start with www.fordparts.com. I just checked they still took a 2005-2006 Ford GT VIN. For most groups there is a picture with part numbers. Some of them you can drill down and get a higher resolution photo. Those photos are the same ones on the CD.
The best pricing on parts was always (for me) Tasca - www.tascaparts.com but theirs won't take a 2005-2006 GT but you can look up by part number or call them.
PS. If you're starting into the DIY service (I did all my own work) then you should also know about the third lift point... You can jack at the center just behind the door and lift both front and rear at the same time to get jack stands underneath. The lift point is the center bar where the two belly pans come together. If you look at the edge by the rocker you'll see the structural part. Be sure to go inboard a little to get it on the frame member and not on the rocker seam like you would do on some types of vehicles. There is a photo of the third lift. I'll try to find it tomorrow.
Edit: Ha! Found it.
Do you have 4 pucks? Dunno what to offer, two chickens? $75+ride
The workshop manual shows two more lift points up front, closer to the body seam too.
