Hello Claudiu @kadudu

The rear tonneau panels (pre facelift) are available from your Jaguar Dealer/Heritage web site currently or David Manners who I use even – part no’s. RTC1646 & RTC1645 – replacements are now actually BHC1374 & BHC1375 almost identical but no oval bumper bolt holes precut (not sure why) – just have to cut.
I would suggest you buy whilst available £173 +vat each seems a lot but there is no option with poor secondhand ones often £100 as are small hand made replacement bottom sections on eBay.

These were out of stock for several years but can be bought now but who knows for how long.
Even I gladly paid the price having tried to source via eBay or anywhere possible for several years – suddenly back in stock so grab them while you can.

Near side wheel arch repair sections no longer available anywhere – again rare on ebay even – but ’Dodford’ in Northampton on eBay can make good replacement sections at a market price, check out the XJS sections he sells..

Regards, Robin
