WT: I've been looking for some time now myself. There are things about each cage commercially manufactured out there that I both like and dislike. I've decided to purchase a bender and do it myself using ideas from various vendors.
But anyway...
http://www.essentiallyoffroad.comAlso try printing out a picture of a cage and ask your local fab shop what it would cost to duplicate. It might be a little more expensive, but you'll get closer to what you want.
Come to think of it, I think Marlin is offering a cage kit.
Go to the main page, and under "Product Showcase" look under "Bumpers, Nerfs, and Armory". :chug:
