The mag catch and safety are interchangeable. Many other parts are too.
But the bolt may or may not be. Just because it fits doesn't mean it will function.
Bolts made for Inland and Auto-Ordnance are not made to GI dimensions. They're real close but not the same. I've tried several GI bolts in the Inland and Auto Ordnance carbines. They fit but wouldn't function at the range.
Others have had different experiences. Possibly due to slight differences in the casting of the receivers that create variables that are inconsistent from one to the next. Most of these differences require close examination. A few don't. The bent receivers being one example. The bend may not be there, may be minimal or may be like the photos shown earlier in this thread.
