Approaching Legendary Status

Cars going down for the winter as of Tommorrow, the other day I got a pretty loud metal on metal grinding coming from somewhere in the drivetrain, and we are thinking its the tail end of the tranny.
One thing we noticed and can't explain when it was on the hoist, was the driveshaft was scored all the way around multiple times, probably about 1.5" past where it goes through the DS safety loop. There is absolutly nothing remotly even close to hitting the shaft in that area. We turned the car on, rand it, and loaded the suspension, and still can't see anything that would cause this.
The tailshaft seems to be making some kind of crunching noise it sounds like (through a screwdriver we listened)
we plan on dropping the pan tommorrow.
I guess my main questions are are
1) what other 4l60e's will bolt up to our car? (I know the v8's won't even if you change the bellhousing due to input shaft sizing) but what about other vehicles? which would be a direct swap? as I am trying to find some lower mileage ones.
2) does the 4l65e bolt up to us without issue? what needs to be addressed with that? and what car can I find these in?
3) wtf could possibly act like a lathe and start chewing into my D/S? This was never there when we swapped the rear end in...so it is something fairly new. NOTHING is within the range of this area.... The only thing we thought was the top of the DS loop, but I am sure the shaft would come through the top of the floor before it could go up that high...
