4 speed with 440

Either brake rod will work IF it is for the brake setup you are using (power or non-power).

Make sure you grab the extra frame side bracket that's welded to the outside of the frame rail. You may or may not be able to make the clutch linkage work, but grab it if it's cheap enough. I've always modified the clutch linkage to suit my needs rather than spend a couple hundred on somebody else's parts. You can also go hydraulic with parts from certain year Dakotas (not sure what years).

Go with whatever clutch size fits the bellhousing you find. There are quality clutch parts out there for both sizes.
