Bought a used grill guard for my disco the other day in a junk yard. Do you guys have any suggestions on how to straightened it out before i install it on my disco. Apparently the guy that used to own it hit a deer on the driver side. That's the reason why its a bit bent on the driver side. I have attached photo what the full bush bar looks like.

 

Be real careful so you don't bend that light tubing, also get rid of any rust and paint before installing.

 

If you have access to an Oxy/acetylene setup with a rosebud tip you might be able to heat up the areas and GENTLY massage it back out. If there are any small kinks in larger tubing you could fill it with Bondo and then sand it smooth. It may not be perfect, but it would most likely only be noticeable to you after you repaint it. Just remember that if it powdercoated, the torch will destroy the powdercoating where you heat it. Also, heating metal and reworking it weakens the strength of the metal, but that seems like light gauge stuff anyway so you're probably not planning on plowing through small trees!
On a side note, I've had tremendous success using Appliance Epoxy to paint things. It comes in a standard spray paint can, but it is surprisingly durable and when you scratch it up, a touch up in the affected area blends beautifully.

Good luck and throw some pics of the Disco with it mounted!

 

See if it will fit as is first, it might not be bend as bad as you think, otherwise all you can do is bend it back.

 

Hell, I can't even see there it's bent.
