Wil sets of Krazy gears and funny bricks and wonder gears all interchange?

I am sorry, but I do not know the answer to this. I only have the Krazy gears at this time.

I don't know for certain but based on the quality of these, my guesstimate is that VERY LITTLE consideration went into safety of these. It is a complete waste of money. The quality is as bad as the worst you can get. I typically buy wooden toys for my twin toddlers but the "gears" were something I thought would be challenging for them. I bought two sets and because I sent them by shipping company to me to Europe, it was too costly to return them. In the trash they went. Don't waste your money. MagnaTiles are a much better long lasting ( yet more expensive) alterntive that will last and keep them interested forever!

Where can I get a replacement piece for a missing piece that it didn't come with?

Well, I would think that AMAZON/Gear Building Toy Co. should send that to you at "NO CHARGE".

Will these parts fit with learning resources gears gears gears! building sets?

No they will not. We have sets like this and we also have the learning resource gears. It is too late for me to return them or I would have so the gears could be used together for me creativity and fun. I will say that while the learning recourses are a little more pricey they seem much easier for my girls (3 and & 5 years) to use.
