360 motor mounts

I'm in desperate need of a pair of 360 biscuit motor mounts for my Demon. I purchased a pair of 318 mounts (that's what I was told) and they are not going to line up in the K frame. I already have new biscuits, just need the metal brackets. Please help if you can, my motor is ready to go in and we're trying to get this car on the track soon.
