Note 1: Spacer 23 is available in increments of .05mm starting at 3.9mm. 3.9mm spacer is part
number GT-3287213. Add 10 to the part number for every 0.05mm over 3.9. For example, if
4.55mm is needed: 4.55-3.9 = .65mm over, 0.65/.05 = 13, 13*10 = 130. Part number for 4.5mm
spacer is 3287213+130 = 3287343.
