Winchester 100 Parts and availability|Restoration, Repair and Maintenance|Forum|Winchester Collector

Hi everyone, and thanks for adding me to this group.  I recently bought a model 100, like I always do, I went first to clean it, now the breach was open, while running a patch through it, the breach slammed shut, and was stuck shut. I tried everything with in reason to try to open, but no luck, and knowing the breach needs to be open to take apart, I was in a pickle. Well, I took out the front sling screw and the screw behind the trigger guard. I got it open enough to see the bolt which had 2 huge burrs, and by the time I got it open enough, used my dremmel tool to remove the burrs. I then was able to part the stock from the guts of the rifle. So while inspecting it, I noticed the trigger housing appeared bent, and very corroded, after trying to clean and get the housing cleaned up, after all that, I attempted to bend the housing , and just made it worse. 

So, anyway, the purpose of this post, is to find a source for 100 rifle parts, Numrich, carries the bolt, but I need a trigger housing, or what Numrich calls it a guard housing assembly, their part # is 509520A, or looking at a diagram it looks to also be #2100. If anyone has any leads, please let me know please. Thanks so much.
