The filter manufacturers have websites.  I never received a reply from Wix, but I received one from Baldwin saying they had not had enough requests to do crossovers from Farmtrac.  Some more requests to their website, or to gjohnikins@baldwinfilter.com or to Gina Johnikins at 1-800-822-5394 would show some interest.  Give them a call or email.
