That's the nice thing about going from wide row to narrow row with the New Idea pickers. You don't have to find different parts. The hood is the main thing. I have wide row hoods on my 327 husking bed, 318 grinder, and 329 sheller. I have a 325 narrow row gathering unit. One side goes into where it is supposed to and you just bolt that one side on. Would work good if you wanted to go from a wide to narrow or narrow to wide gathering unit quickly.
