frame repair

[Beefcake]

I have the most crappy truck on this board. I love the thing, dont want to part with it. Its a huge eye sore, but I dont care. As long as its useful and cures my wrench'n itch. Im happy.

In its previous life, the truck worked on a farm. Probley lots of hours idling with half an exhaust. Well, I was underneath the truck the other day and noticed big chunks of rust coming off the frame. There is a huge section that spans about 3 feet thats just rotten on both sides. From the cab to about where the axle bend starts. Worst part is, i see an actual crack that is about an inch long on the drivers side.

Now i know most you guys would have scrapped this thing a long time ago. But the wife doesnt really give me much in the form of an allowance. IF i get rid of this truck, i doubt ill ever have another one.

so im wondering what the best fix is (assuming i work with what i have)

a. cut the frame from the cab back and replace with non-rusty long horn frame.

b. weld in patches to existing frame.

c. weld in tubular stock.

d. other.
