I have followed this post for quite a while. I have really enjoyed reading about your experiences with your GTX. That car is really neat and I'm so glad to see someone really enjoying their hemi car the way the designers and engineers envisioned these cars being used. They were never designed to static objects of art. They were built to show Chrysler's engineering dominance.
You have soul-mate out west. I love beating on my 68 Hemi Charger. It is an original hemi 4-speed car that ,like yours, was purchased as a rolling body only.
Keep on stompin' that elephant buddy!!!
