ive got stock size GRP "wings" (fenders) from day mouldings here in the UK.. they are better than NOS steel wings IMO as they fit the same, but dont rust.. EVER! even the captive threads in the headlamp bowls are brass and the top lip that holds the light in place is stainless.. all bonded in. best bit is that you can get all 4 for the same price as one NOS version and you can order them in a gelcoat finish in virtually any 70's vw colour!
3 month waiting list though
and i have no idea where "AB" is so this may be of no use to you?
