Thank you everyone for all your information and support.
Wow I am continually amazed with everyone on this forum, how so very helpful you are sharing your experiences and knowledge. Once again you have shared so much more than I imagined or even thought of.
I lay awake nights thinking of each step of this build process.
I can only do like one step at a time processing and visualizing how to resolve all the unknown unknowns which keep coming up each step of the way. Just like the charcoal canister being so big.
The New York, minimal rust has turned out to be, one can say a mountain of rust. I believe we finally had discovered the last hole in the floor pan. Three cut outs and patches, both rear lower quarter panel corners cut out and replaced inside and out, about 20" in front of the left rear tire, over 3 1/2'of 1/4" X 3" steel stock all welded in now and finally back to just the lower body work. Feels good, looking forward to interior build end of next week.
I am grateful for all your help.
