Definitely coming along nicely. Did a similar project on son's 2011 Kia a few years back. I know the cutting/swearing thing works...did it a lot.
Many issues w/ all the rust/stuck areas & the final day I literally threw out my back picking up the torque wrench. >.< Getting old sux , but your "Stang's going to ride & drive like a dream again. great work!.
