Sounds like someone added long shackles to a saggy spring , like Bob says... I think you "may" need new leafs? but the correct are also shackles ,but shorter...readily available , from for instance Classic ind., after having been present when someone else just took 'oversize' shackles out , be prepared to have 'fun' time getting the rubber pieces out for the old bushings ...his was really stuck....best way to get to the old is to drop the tank.... you`re going to say "yeah right, like I`m gonna do that" , but if you dont ,you`ll prob say later ,"Yeah I should have dropped the tank"...this case took 5 hrs, 3.5 or more was to remove the rubber bushings w little pliers etc...theres no way to get a drill or anything in there! but with tank dropped, yes! You can try first w/o dropping the tank ,but my advise woyuld be to have very little in it when you jack it up or put on a lift so when they wont come out , you can drop the tank... just mho..
