Ok, so with this truck I just bought, there are a few things I want to remove, but know nothing about. I haven't ever worked on a Chevy truck.

I know right?
(I've been working on Fords for a while... Mostly because my friend got his hands on a '67 Mustang GTA)
So I said, I need more power than that. and thats where I am at now. Proud owner of a '75 Chevy C-10 Silverado LWB Heavy Half.
Well through the years some unwanted stuff has been added to the truck (unwanted by me)
- A heavy duty bumper w/ hitch
- A brake controller
- A camper shell
- An aftermarket dual gas tank setup...
- And the dreaded speaker holes in the doors...
I am just wondering if anyone would possibly know how to get rid of these, or if anyone would want any after they are removed.
(Camper shell i can handle xD)
the ones i really am not sure about are the Brake Controller, and the Aftermarket dual gas tank setup... (uses the original and another.) Anyone know what I would need to do to remove them. Any help getting me set in the right direction is great.
I love this forum, you all have been such a help!

Rock on guys!
