Replacing a crank shaft questions
Why do I feel like a dentist here? It's like pulling teeth to get any basic info. What exactly are you trying to build? Stock-ish shortblock? Stroker? Why does the shop deem your crank to be toast? If it's scored, a light grind to the smallest undersize takes care of that. Is it twisted? Or do they just want to take more of your money?
You asked for advice- give us some info. Pics are nice but they don't tell you journal condition or if it's been ground or to what undersize... We're just trying give you the answers you need and maybe save you some grief along the way. This isn't the Manhattan Project, no need for secrets.
