Im not completely sure of the differences between the 216, 235 and 261 but would it be possible to just have two sets of brackets, 1 for the 216 and early 235 and another for the later 235 and 261.
If I can get measurements of the 3 series that would be great. I have the early 235 covered as mine is a 54, which I imagine would work for the 216 so I need the later 235 and 261.
