Replacement inductors for 3.1 tl

greetings, ive been researching for a couple of days and cannot seem to find a replacement sub-bass inductor for my 3.1 tl's. aboutvto go through a massive rebuild and was wondering if i should just reuse the old one even though its not the original? plastic standoffs are non replaceable but are still intact and it has ferrous screws holding it in place. anywho, just wondering what my options are for doing it as correctly as humanly possible. thank you
