When I enquired, the BTR shaft came with bearings from TK002 trunnion kit.

Have you considered the YT YT6667? They shipped a bad batch many years ago, have not read negatives after that time frame.

ENQUIRE VS. INQUIRE
What's the difference between enquire and inquire?

Enquire and inquire mean the same thing: to ask, to seek information, or to investigate. Enquire is a less common variant of inquire.
Their noun forms—enquiry and inquiry—also have the same meanings: a question, an investigation, a request for information, or the process of seeking information.
Both inquire and enquire are somewhat formal. Some speakers of British English may use both words, preferring enquire in contexts that are less formal. In the U.S., enquire is rarely used.
Here’s an example of enquire used correctly in a sentence.
Example: I’m calling to enquire about the open position.
