diffrence between 3003 alloy, and 7075 t6??

[BrianG]

For a Jato, it *might* be ok depending how it was designed and the size/weight of the motor. But for all the work required to make the mounts, I would do it right the first time with the proper material. Can you send back that 3003 stuff, get a refund, and order from onlineMetals.com?

And, why would a place send something else that is not even close to what your ordered? It would be like me going to a Honda dealership to get a Civic, and they give me a Kia Rio instead because they don't have any Civics in stock. Sounds like a crappy place to me...
