CA WTB: Looking for Powerglide Pivot Shaft from Frame

[NVS-C10]

I'm looking for a Powerglide pivot shaft. This is the bracket that attaches to the frame with a pin/shaft sticking out that the linkage pivots on.

This is the bracket attached to the driver side of the frame (inside):




It's the black pin in this picture:




Can also be seen in bottom left of this illustration:





Thanks,

Nicky!!
