New member with 57 panel

[OnePunch]

Greeting everyone,

I'm the "potentially" proud owner of a 57 panel 1 ton. (pics coming once its actually here). My vision for it is to be basically a rolling billboard for my furniture store handling the light deliveries. I would love to hear input regarding the rarity (or commonality) of the 3800 series panels. Also being a 69-70 Cougar enthusiast, I was curious if there was any consensus among the bowtie faithful in regards to the "custom vs. stock" argument. In the Cougar world, if its a rare vehicle, doing ANYTHING other than a factory correct resto is akin to pushing a nun down a flight of stairs. I'm not really concerned with the end value after its done, because a 55-57 panel is something I've always wanted to have, so I'm quite fine with spending 25k on the resto only for the truck to be worth 10-15k afterwards lol.

I would also appreciate a heads up on parts suppliers for tri-5 panels. If I'm not mistaken, from the door jamb forward everything is the same as the pickups, but there may be a unique thing here or there that I might end up needing. I know for sure I need a drivers and passenger door, and I'll be having the "find a decent used one" vs. "buy a new repop that probably won't fit right" debate in the coming months.

Any feedback is certainly appreciated!

Thanks............
