I do use the angle iron trick for longer cuts but the wavy bracket started out as a rectangle and i didnt cut it into the angled shape until I had the tubes welded on the end so I couldnt have used the angle iron. I thought about building a new crossmember, but decided not too because after I built the engine and tranny crossmember, I was crossmembered out. At this point, I'm gonna see how well the normal frame holds up and if there are issues, I'll box it.
