This is gonna sound REAL stupid, but I don't have a lot of knowledge about the stovebolt sixes, so I thought I'd ask those who know. What aftermarket manufacturers out there make spin-on (cartridge) oil filter adapters for these puppies. I looked around on some of the parts links and couldn't find anything(did find a TH350, 400, 2004R, 700R4, etc to inline adapter though...) All this discussion on here about straight sixes has me thinking that when I FINALLY get my dream truck, it might be best (or at least cool) to keep the six. Thanks for any help you all can offer.
