The pictures are great but now I'm wondering if I have a spin on filter like the picture or the complicated looking thing in my service manual. That one has a canister bolted on the top with the cartridge inside. The Detroit dealer in town suggested I change the whole dryer if it does not have a spin on cartridge. What do you guys think about that? I have access to a shop with a pit, that should make the job simpler shouldn't it? At least the bus can't fall down on me.
