Bad rail beams are common in Z's at least all the ones i have looked at mine has the problem, what i am going to do is have my dad's friend take his welding torch and cut out the bottom half of the I_I so it looks like this I I them i am going to get C or U channel and bolt and wled it on to the I I giving me a new I_I fram rail, it going cost me like $200 to do the whole thing. I would say its well worth it. go to the local high school, most schools do body work and the only thing you have to pay for is parts not labor, and they have to tools to do it.
Let me know what you get for a deal from them, but goto a high school and check out what it would cost for them to do it.
