Ditto to Waldo's comments. Those motor mounts are stronger than you think. JB Weld would be just the thing to fill the holes. You could move the engine forward or backward if it is possible or even try to drill in the same area. I should also inject that I have a Sig mount in my Twist.[] It doesn't matter if some or all of the holes are a little large. You can always use washers before you put the lock nuts on the screws. Is it mangled?[:@]
