Default Columbia Syncro Clutch Assembly

I am working on a Columbia 2 speed rear and noticed that there are two different synchro clutch designs. Is one superior over the other ? I believe the wide tooth one came from a 36 and the narrow tooth from a later model

My 40 has wide tooth design, I would guess it is later design with wider teeth
quicker quieter engagement..I am always cautious when shifting to allow easy low torque
engagement of mine, but occasionally have not, which is unnerving/

The later parts are considered a little bit better, but there is nothing bad about the 12 tooth. The 12 tooth is pre-war and the 24 is 46-48. Assemble the clutch over a sun gear so you wind up with the proper alignment when finished.

Thanks guys for your input. That makes sense as I have a 36 and also most of a 48 unit that was broken and I am trying to piece together for my 32 Pickup. I have already spliced and narrowed the early and late tubes together. John Connelly’s clutch kit instructions state that also. He states to insert one of the springs,shoe, and linings In a cavity. Then insert the sun gear then install the syncro slider and align the cogs. I quickly found out why as it was pretty tight with just one set in it.
