I'm new to fabrication and welding, I'd just like to share my idea and hope it helps someone. Be easy on me.

I removed the tank from the cab and put in a "under bed" tank. I was left with a hole in the cab. I'm not a good enough welder to put a shave plate and I'm definitely too broke to paint after that. So I decided to modify a cap to seal the hole and, as a plus, retain the stock look.

Here is the Video for those interested

And here is the tutorial for those that prefer pictures.

Supplies:
4 inches of all thread and 2 matching nuts ... or bolt and nut.
Gas Cap from auto part store
Filler neck grommet
Some thin metal for making a huge washer.
Optional: peel and seal or equivalent

Tools:
Welder: Or epoxy, JB Weld, Etc.
Something to cut metal: I used a cheap jigsaw and metal cutting blades
Drill and drill bit slightly larger than thread width

Get yourself a cap for under $10 at the local auto part store. Weld a nut on the inside of the cap. You can also use epoxy, JB Weld, or some other adhesive if you don't have a welder.

Screw in some all thread and tack it so it wont spin off

Or, you can just use a bolt instead of a nut and thread.
