By the time you ship them, it wouldn't be worth getting them for free. How far are you from Hoboken? I have a friend driving here for the holidays who may bring them back for a couple of bucks.
Welcome! You must be the #1 Mustang fan of all time. Just doing the math, you wanted one a full 5 years before the Mustang debut'ed in 1964 1/2. ;') LOL
What size do you need. I have a pair of 245/45ZR17 in my basement from a 2002 Mustang GT that i used to have. They are 90% brand new. You can have them for free.
