Welding isn't a skill that is one size meets all.... some times you have to skip around - and sometimes that will cause more warpage than if you'd have just gone full boogie.... the learning curve is a long steep one. LOL
The guys that do this for a living - day in and day out - they can tell what to do just by looking at something.... ME.... I just pray I don't warp too badly.
Firewall looks great! I didn't know Direct did that! Good to know!
