97 Sable Correct Synchronizer install

Does anyone have the written procedures for the synchronizer shaft install? I did replace it without the alignment tool. I marked everything and made sure that I got it back to the original position, but now I'm not sure. Readout is saying idle ign adv is 20-22 deg and load adv is 40 deg?!? Also am getting a DTC P0340 which is Camshaft Position Sensor Malfunction. Can anyone help with the correct install procedures? Autozone had a diagram of the correct degree setting but neglects to tell you where the crank should be, I assume TDC. Thanks

my sychronizer tab was sheared off. what was the position of your tab in relation to the grank?
