If you still have all the metal pieces from the forearm you can usually find a stripped forearm on Ebay or Gunbroker.
The hard part is having a T/D without the forearm metals, they're the hard thing to find.
Also make sure the barrel isn't seized as sometimes they did from sitting to long without being removed.
A lot of times what happens is under the forearm is a small square hole Savage mounted there as a lever. You would move the forearm forward after removing it and put the takedown latch on the barrel into the small square hole in the forearm, then turn it to remove the forearm. The problem was that if the barrel was seized it didn't take much to push to hard on the side of the forearm and end up breaking it or giving it a good crack.
