Where can I find the codes front springs previous for some reason removed springs where are the codes on the rears
Read RPO label next to brake MC.
You don't need to match RPO label.
You do need to make sure front springs match each other. Example both are HZ.
You don't want 1 HZ and other HW. This can cause same problem as 1 tire w/ low air.
You can still find springs w/ own label from factory but many have fallen off.
