Thanks guys,
AUS808 - RAMPZ Pads - Google doesn't bring much (?)
GrumpySmurf - just checked with SurfSail - nothing available.
Mark - Thanks, I'll measure the pad and PM-you tomorrow night.
Hopefully there will be enough for two fitting direction wise
Glue...
The front pad also got unglued a few months ago - and I glued it back using Sellys Contact Adhesive. Seems to hold so far.
The exposed is dark yellow coloured - very likely the same contact adhesive. A bit of a concern.... maybe it was glued impatiently.
Not sure how to clean it either. Someone was promoting MS Polymer glues on the forums, and UHU Max Repair.
