CAN bus split termination impedance - no 60 ohm resistors?
You'll be lucky if the average differential characteristic impedance of your transmission line is within +/- 10% of the nominal 120 ohms; small inaccuracies in the termination network will not have a significant effect. 2x 60.4 ohms will be fine. Even 2x 62 ohms (E24) would be fine. Better to go slightly higher than nominal rather than sightly lower, since the receiver IC will have a couple of kiloohms of effective input differential impedance which will act in parallel with your termination network, lowering the combined impedance seen by the line.
