Sills required Inner & Outer N & O/S. - Sup Recommendation?

[Lord Sladacre]

I would be extremely grateful if any member could recommend a supplier of high quality replacement sills, both inner and outer. I also need the lower front rear wheel arch panels - evidence of "moth" attacking. The well known corrosion problem is endangering the life of my 2003 S - Type. SNG Barratt can offer LH but not RH neither can jaguar. I have a very competent fabricator garage inline prepared to do the work c £3k. Scary, but no viable alternative. Any all help much appreciated. Thank you. Dominic
