"This is a modified AMT kit. I fixed the roll cage, swapped out a lot of engine parts, and changed the wheels and tires."
awesome!!,, those old AMT frames can be a pain to assemble,, did you scratch build all the lines or are they from a die cast???
You have a great heard of Mustangs.
Lots of scratchbuilding. Suspension rods are craftwire. Fuel lines are solder. Solder is great for its softness and flexability. Roll cage area was corrected with heat shaped plastic tubing. thanks for looking.
