Dan I would check the filter but you do not need to take it somewhere other than ease factor. The skin of filter is thin and easy to cut, a hacksaw to about anything you may have will work. Just be carefull not to add a Doctors visit for stiches. Cut it at top near face of threaded end and not the bottom for best results.
A machine shop may be good source to help identify pieces you found.
