Seven,
First of all, I haven't said hello to you, so welcome to the site, I hope you find it helpful and "entertaining" at the same time.....
Second of all do you own a Parts Manual for your bike yet, if you do post the part number here for the exact part or associated parts you are looking for, if you don't have it elvislee will have it or them for sure since I believe he owns a FXR4 and I believe has a parts book at his disposal and we can then get him to post it and we can sort of do a "regional" search to help you find it by calling a couple of our own "local" dealerships to see if we can help you get it.....typically HD Dealerships have computer reference ability to determine whether certain parts are either in their own part's departments or within a "so many" state region.....this would be a way to help you locate what might be referred to as a "NOS" part, which stands for New Old Stock, if such a part number is no longer a replenishable part, (if that makes sense).
Perhaps someone else here might have even a "better" idea or even has one for you.
Keep us posted.
Regards,
Tim
