Was it a big task? It is all relative, once we had raised the roof with the original header still attached, I made a fibreglass insetso the screens are glue in now. The screens were easy because they are flat laminated glass which almost any glazier can provide. The corner lights are lexan and supposedly scratch proof, I built a mould for the lexan to be formed over and I have kept that for posterity. I am happy that we have eliminated the water ingress via the windscreen rubbers which was the only real Frame rust area under the original screens.
Of course I did have a rusted out folly over the driver's side wheel arch courtesy of 19 years of spillage from the drinking water fountain, but that is almost standard with these things.
Cheers Alan
