center cross tube question

[ejmw7762@netscape.net (EJMW)]

I recently purchased rubber bushings from Rick for my center cross tube for 
my serII.

Rick said I should push out the metal collar inside either end of the cross 
tube in order for these bushings to fit.  However, it seems as though the 
collars are of one piece and there is no way the bushings will fit inside.

Do I have an odd center arm?  Are Ricks bushings incorrect?  Am I missing the 
obvious?  

Any help or suggestions appreciated.
