I am going to use them to make a YZ 125 engine mount. If I have these then I can just weld the supports to them directly. Right now I don't want to spend the 200$ on the mount.
That is what I originally had mocked up. I bought some aluminum GX mounts and was going to just bolt a solid sheet of steel to it. Then weld the supports to the steel but this puts the engine a little higher then I want it because the supports are so thick.
