can anybody tell me wat gauge of steel would be the best to build an exo skeleton roll cage? Or any  other suggestions would be appriciated?  

For what vehicle?

If it's a Jeep or other small SUV, 1 1/2" .120 should work fine. I'd suggest 1 3/4" .120 DOM, but that is just me. Can't put a price on your life you know...  

well its an 81 toyota pickup, so ya its pretty small  

I was wondering if anyone new some good 17X10 wheels. It seems like newer model vehicles these days only accept big wheels, which explains the reason that I see so many with 20" rims with very narrow low profile tires. I'm looking for minimum size of 17" but I want a 10 or 12 wide so I can put some meat on. I had a 96 dodge with 6" of lift and 36X13.5" swampers years ago. I have been into street rigs since then but I'm ready to come back to 4 wheeling and the whole tire and wheel thing has changed so much that I don't even know what to buy. I mean can I even buy a deep dish 20? Please tell me where to look because the sites that I have been to only have very narrow wheels which aren't appealing to me at all. Even with 20's, most tires only go up to a 35 and then straight to 49's or bigger. Please forgive me for I haven't done alot of research yet but I want to buy soon.
