If the linkage will hit on stuff, it needs to have a curve bent into it for clearance around whatever. (Steering link on my narrow-front tractor looked almost like a "?") Adding the curve will use up more rod length than when it was straight, and it's not quite as strong as a straight rod.

I think we all *try* to avoid mistakes. They happen, and on toys like these it's usually fixable. Knowing some fixes helps it be less scary to tear into converting old / rare / expensive toys.

For strength I generally like the 24-hr cure epoxys, or metal-reinforced stuff that can be drilled & tapped. 2-part mix and the putty you knead together both have their uses.
