Speedway has a universal bracket set that bolts between the engine and the bell housing! I've used it on automatic transmission installations and it works great!!
You'll probably have to come up with some sort of rubber biscuit mounts like a tri-five Chevy uses and maybe fabricate the attaching points for the frame.
I don't know how it will work with a manual transmission. I had to space the torque converter back off of the flex plate the thickness of the brackets to make it work.
