Welcome Monica,
First of all It's your truck and you should build it the way you want it. If you are using all vintage parts, I think you should be allowed in the "stock" class at the shows. So what if something isn't exactly like it came from the factory. I like to go to the shows to see what everybody else is doing and show off my truck. I don't care about trophies or anybodys critiques, but that's just me.
