I have an older set of Koni's on my Dart. These are the one's that you have to remove and twist or turn to adjust. Anyone have a link or can explain how these work. Tried a search here and Koni's site but came up empty.

mine are from 1988 still on car just readjusted them you have to screw the spanner nuts down pull the retainer at top that holds spring ,collasp shock turn in or out .You will feel it easier or harder now.Make sure you measure where the shock eyelets are or threads at bottom tospanners.
good luck don

Sorry, should have been more clear in my post. These are not coilovers, there spa1's. Looks like a stock shock. I think I remember having to collapse the shock to adjust it.
