Hey bud, you can get them brand new from J.A. Milton for just a couple of quid. I keep meaning to order some for mine, I’ve got a couple of repaired ones using electrical connectors that have been like that for a year or two or so. I also found that tying the springs together hog ring style everywhere has actually made them a nicer ride too, I used cable ties and wrapped them around twice but didn’t pull them tight and let the bum tighten them up . I suppose you could even double on the springs if you wanted too, for what they cost.
