I just bought a new (to me) truck and I'm looking to add a steering box brace. I took the one off my 2003 3500 4x4 and I was going to sell it and buy a new one for my 2011 2500 4x4....turns out I'm pretty cheap. What's the difference between the 2? Is it just the pitman nut that's a different size and I can just get that and use the old one or are they completely different braces and I'll never make it fit?

Old truck
2003 3500 Quad cab sb 4x4

New truck
2011 2500 Mega cab 4x4
