67 trailing arm question

[67targa]

Hello, I am hanging my suspension this weekend so I am staging the parts today. I cataloged everything but there is 1 piece missing.
So I am calling on any Pelican who might have one,,,I need one. This is the spacer that is between the inner and outer bearings. I do not know what other years this piece was used. I could machine one if needed, hopefully someone out there has one.

They were only used on the SWB cars. Part number 90133126101, Pelican can order it for you, cost of $71.25

My arms are back together now, but I seem to recall there is a slight step to this on the inside and it must be installed one way for the stub axle to slide into it.
