Have you looked through the Melvin's catalog? http://www.melvinsclassicfordparts.com/pdfs/maverick/Melvins_2017_Maverick_Catalog.pdf
I also found out that the front and rear small bumpers and attaching brackets will be available in the same time frame. The floor pan is being designed as a 1 piece pan, modeled after the early(pre converter) Mavericks. Rear valances are now available and hood hinges are coming in 2 weeks!
Even if you have a Maverick/Comet with good sheet metal, this is great news. I'm always thinking about damage and how will I get replacement parts in the future. I feel good about my Maverick. Not so good about my Thunderbird.
