Tim, Didn't you find the Koni a bit hard on the Girdraulic fork, even if you sourced the correct Koni front shock, 76F-1239, I think back in the day the best way to go was Series D Armstrong with longer eye bolts, Thornton is/was great, sadly no longer available, but luckily we have AVO that seems infinitely adjustable in manufacture if you know what to specify.
