scout 2 classic 2" platter not switchable to a classic 2 , the bearing taper different.

Am going to sell a almost new 2" classic platter and found out on my own it will not work on a classic table even though it a classic platter, bearing assy are different taper  scout classic sits too far down on a classic table and wont rotate freely. At least i know to make it a specific sale for a scout 1 upgrade .
