Thank you Guys. Those holes probably had something to do with the crack, but there is a bolthole in the bottom of the frame, [where the running board bracket bolted on at] that was more guilty. Also, farmers are really bad,[notorious even] for overloading their trucks, and the PO picked rocks off his fields and overloaded this poor little truck something awful.
Anyhow, today I did some brakeline and fuel line work. A number of things went wrong, so not a good day. I needed a line that had two different size ends, and I didn't figure it out until quite a bit of time was wasted. Then another line was mislabeled, and must have been a metric size, so would not screw into anywhere. I also didn't figure that out until some time was wasted. My fuel line had to be 81" long, so I spliced two lengths together and carefully measured the distance needed again. I cut the line a wee bit too long on purpose, then practiced double flaring the throw away piece. It came out pretty nice, with this newish and expensive tool. I got confident and cut off my fuel line to the right length and flared it, ------- badly, so I had to cut the line a wee bit shorter again. Luckily, then it was suppertime, and that went well.
