This last month I started building the same improved linkage design for the 235 models with Esco struts. A number of 235 owners have been waiting for this and a number chipped in to help gather measurements and other information needed to ensure they will fit. Turns out the 235 linkage is nearly identical to the 320/360 except its length and a few other small details that don't matter.
Since the first time I ever made these I've made huge improvements to the tooling, setup is a lot easier and more consistent then the methods I showed initially.
I can't share it all here but the fixture below I'm pretty proud of as it allows me to precisely cut the slots in the linkage without the clamp compressing it, and without chatter. This is done by using rubber to lightly hold the unsupported section and then firmly clamping the solid section of the part. With out this rubber support it would become a tuning fork, and if it were clamped firmly the slot would become tapered due to the flex caused by the clamp while cutting.
Currently I'm wrapping up machining them and will send off to Anodize, everyone should see them on the website shortly. Next up, GM27 brackets for 320, 360, and the 235 (yes we found these are also unique on the 235). Then I can "finally" finish nose fork components, something I'm super excited about.
