Frame rotted at steering box - K2500 Suburban

[RobK]

So my frame completely disintegrated at the steering box. Finding a K2500 Suburban in the yards is virtually impossible in my area. Will the forward frame section (ahead of the control arm mounts) from any other trucks work? I'm guessing that the front section from a pickup is probably the same. I spent some time under some K1500 pickups today and they LOOK the same, but I'm not 100% certain. At a minimum, the configuration with the front crossmember, sway bar bracket, etc. looks exactly the same.

Anyone else been down this road before? I know there are dozens of different frames under GMT400 trucks, but it seems that the bulk of the differences are from the firewall back.

Thanks in advance for any help guys!
