Mike,
I think you mean the big pin that the lever pivots on?
Not there on my 465.
I have to make a plate to mount the 420 parts, and a clevis to use as an adapter to connect the cable from the drum brake to the linkage from the lever.

The pivot pin is not there on all SM420 top plates either. If the SM420 came out of a smaller truck, the pin is not there and the hole is not there to press the pin into. I have drilled a hole for that pin on a couple of top plates. I am not sure about the SM465 if the boss for that pin is there or not. (I don't have any SM465s laying around).
