See the link:

TSA Permitted and Prohibited Items List

it took me about 10 seconds to find this list on Google.

Shouldn't have taken 10 seconds since I provided the link in my last post.

The trouble is not whether the parts are "allowed" in checked baggage. The trouble is if the parts need to be declared.

The rule doesn't specifically say no and BELIEVE me, if it doesn't say no, someone in TSA will find a reason it implies yes.
