The info in the link that Tow Guys posted is excellent to follow. That should make the spliced frame as strong or stronger than the original frame in that area.

Yes, I forgot to highlight that part of the conversion. That seems to be the way to do that sectioning as it will be stronger than a straight cut.
Best of luck with your project!

We have been cutting and splicing class 8 trucks at an angle foe 40 years or so with no failures.
