I am very sorry to hear about your personal tragedy...I have spent way too much time in the hospital the last few years myself.

Suffice to say, you have my well wishes.

To get back to technicalities...as an aircraft mechanic, you should have access to decent measuring tools.

Why throw good money after bad?

Split the case and start measuring.

If it specs, roll with it..if it doesn't dump it.

Check each piece.

Do not slap a new top end on an unknown bottom end.
