Dimension Help, Please

[VicenteRC]

Bob:

I think Gerald is right.  I replaced my old YS 140 FZ with an OS 140 RX 
and the OS was a little shorter.  I was in a hurry so I installed a 
flat washer behind the spinner plate.  You will need to replace the 
nose ring.

The OS 140 RX was in a Focus. I installed a 3M 140 and they are exactly 
equal.
