Help! turn signal switch reassembly order

[chevy72blu]

I was able to remove my broken turn signal assembly and replace it with a borg warner unit. However, I stupidly didnt take pictures along the way and it was a few days ago when I started the project.

I have the new unit installed as far as this step:


However, I still have to install the cancelling cam and this rubber spacer. The spacer will not fit over the back of the cam and it obviously doesnt go over the front. Should I have installed it between the shifter body and turn signal assembly housing?

The offending part:


I cannot find a clear exploded view in either my assembly manual or LMC.

Any help would be greatly appreciated!!
