2 Questions (Gas tank & Exhaust System)

[1stford]

Still having problems posting pictures of my project so hoping one day I will figure that out. I do have 3 questions that I'm hoping to get some info on so thank you in advance for the help. 1936 Ford Truck. I'm trying to keep it "Pretty close" to original.

1). I have a gas tank and its in good shape but want it restored. Is there a best way to restore it on my own, send it to someone to do it, or a good tank to buy to replace it.

2). Need to do exhaust and wondering what is the best system to buy to make it original, maybe someone who specializes in it.

3). Have the original radiator and need it to be rebuilt. Any experience on having one redone vs having one from someone like Walker in Memphis.

Thanks so much.
