Float-A-Motor mounts

[stillwater]

I am putting a B engine/B trans in my 30 pickup. I have heard that the mount I need to use is a Float-A-Motor mount. However I have heard some concerns from a few folks that the Float-A-Motor mount is not believed to be a safe way to mount the drive train in my truck.

Does anyone have some advice for me, one way or the other on this subject?

If this is not a safe way to mount it all up, any ideas on what is?
