    Default Van Spring Options

    Well, it appears, as with most old vehicles, that the leaf springs on my G20 have sagged, and as such my pinion angle is now virtually flat, causing some driveline vibrations.

    So, As I see it, my options are:
    -- Replace the old springs with new ones (yay!)
    -- Add some helper springs to get it sitting back at right height
    -- Add air ride assist of some sort (additional bags or shocks) to boost it up

    Obviously the springs will be a bear to change, as it's an 86 and got 25 years of rust going on. however I think i can get a sawsall in there ok to cut the bolts, making it a little easier.

    The shocks on the back are in need of replacing, so it would seem like that would be a good option.

    I have no experience with the helper springs, so don't know if it'll give me the "lift" back up that i need to get the pinion angle back.

    Are there other options I'm missing? What would you all suggest?

    Another option, I thought of, are coilover shocks/springs, instead of air ride shocks. but I'm not sure either air-ride shocks or coilovers will give me the increased pinion angle that i need.

    No one has done anything in this realm, or has any insight here at all?
