New Jeep with a little mud on it. (Large Pics)
I wouldn't think that finding axles in LA would be that difficult. They grow on trees in 'bama. I've got a 3/4 ton tree in the back yard that's ready to bloom. You want some? (kidding)
You should be able to find a 3/4 or 1 ton Ford sitting by some old lady's barn just beggin to be picked clean. If you truly want to run the 38's then its the only way to go. You can get weld on fullwidth kits from
www.bluetorchfab.com It incorporates a new bumper and shackle reversal with the setup. It's almost too easy and looks pimpin. Then all you have to do is weld one perch on the front and two on the rear.
For steering, the chevy pump is probably the same as the one you have now. I believe both were made by Saginaw they just use different mounts. If you are not going get in the rocks, then you can get away with using the factory power steering with the bent drag link.
You could probably get away with running the factory springs done SOA. It will give you 5-6" of lift then if you need it you have the body lift to fall back on.
It's better to do it right once than buy a set of high dollar wheels only to break axles then upgrade and have to buy another set of 8 lug wheels (cause I guarantee that if you put a 38" Bogger on there, you're not going back).
BTW...check E-bay for axles if you get desperate.
