It's mounting it that seems to be the problem though I've spent all day out in the garden trying to piece something together
Closest i've come is mounting an Avid IS-203mm post mount on the dropouts,Clipping a spring into one of the holes and attaching the other side to the 4 bolt mounts. Then running a rod through another hole and mounting a Jocky on the rod but i can't seem to keep it in the same place
I have limited resources though, Couple of Sockets/Ratchet, adjustable spanner, cheap Alan keys, pliers, Penknife style hacksaw etc. A f**ked rear mech and some random bolts
Edit: I'm sure it's still possible Daniel
