Is the question do you *want* to sell it or do you *need* to sell it?
If you need to sell it, sell it. If not, decide if you want to do the restoration or preservation. If ya got it in ya, keep it. They are getting harder to find all the time, so if you like it, and you don't have to sell it, keep it for now and see if you get into it. It sounds like a pretty decent truck and those bigger Art Decos aren't all that numerous.
Just think it out, don't get in a rush and do something you may regret in a while. If it's gotta go, then so be it. But if it doesn't, let 'er sit a spell. Drive it around for awhile and have fun with it. Take it to some cruise-ins. Find your local ATHS or VCCA chapter (usually, the ATHS chapters like unrestored survivors as much as show queens) and enjoy the comraderie of being around the gang, and you'll enjoy having the truck a lot more.
Hope this helps,
John
