Thanks, Brad, for backing me up, even though you're selling yours for considerably less.
Boobala, are you an engineer or machinist? To make these mounts the way you want them for less than $250 would be an incredibly great deal ($250 is my reserve price, by the way), if you don't have to do the research and development work. I could do it the way you would like them done with all the radiuses and corners, but it would cost considerably more. I'm selling these because I made a few only, there's not a massive demand for these parts. I could sell them cheaper if I had hundreds of customers wanting these, so I could offset my costs (supply and demand I'm not trying to rip anyone off with that price, I think it's reasonable for the quality put into it.
Oh yeah, these mounts do not bolt right onto the crossmember mounts of the car. They will bolt up to a pair of heavy duty rubber insulators, and from a machinist point of view, I don't think these mounts will crack over a few hundred hours, like you suggested. I've had mine for a few years now, and there is no wear and tear on them, because they are so thick in construction.
If you can make these mounts for cheaper than $250, and the way you want them with all the radiuses, I'll buy them off you!
