Been having a problem with the front bags going down whether sitting over night and sometimes driving. I took the air soleniods off and found one had the orings in the wrong place? put them back and put some vacuum grease on them and also took the other side ( they seemed like they were correct) put vacuum grease on them and overnight the car didnt go down. I am still thinking about replacing the fronts with springs. Can I leave the rear bags in? or is this a good idea? Also heard the rear shocks from 95-97 Tbird will replace the rear shocks on this 95 Mark VIII ( O'Reillys said they dont carry shocks for that car?) Anyone know if this is true? Thanks, Tom
