For what it's worth, I just hit a deer in mine about a month ago. It messed up my bumper and grill. I pulled the bumper to see if there was any other damage and found the frame bent and cracked in the same place yours is (but not as bad). The leafs and hangars were bent too. Insurance didn't total it out and wrote me a check to have the frame swapped. You have much more damage than I did but they valued my truck at $5500 (94 IDIT with 175k, auto trans 4x4, extended cab xlt). So they wrote me a check for $4100.
I was also going to say I have an 86 cclb you could have once I'm done pulling the axles (for the frame), but your profile says you're in Texas and I'm in Washington.
