Fabulous project! I'm really enjoying your work and you're doing a great job with this!
I have a somewhat similar project in mind. I want to build a T altered completely out of AMT Parts Pack parts--body, frame, engine, wheels. Body will be the AMT comp T (just ordered one), frame the parts pack rod frame (yeah, I know it's basically a street rod frame, but the sprung rear suspension will be hidden under the body), engine parts pack blown Pontiac, wheels from the parts pack. I don't have original parts pack tires, but I ordered the new ones and will try to use those if possible; if not, I'll use something from a pre-1967 kit. Any other parts I need along the way will be sourced from pre-'67 kits. I'm going for somewhere in the 1964 to '66 timeframe, something similar in appearance to the Jewel T but in metalflake blue (vintage Testor 'flake, of course). I wanna see if I can build it using all mid-'60s parts and materials, using my 2014 skills, airbrush, adhesives, and so forth.
Meanwhile, I'll be following yours for inspiration. Model on!
