As Griffiths and Chimaeras age there are an increasing number of owners seeking replacement dash panels for their cars. Moisture and heat can easily damage the thin veneer on these cars and obtaining replacement parts at reasonable prices can be tricky - particularly with the variations in dashboard style that came our of Blackpool in the 90's.
There are two companies currently offering solutions to the problem. The first is London Carriage Craft. Set up by a gent who's spent much of his life working on hand built British Cars, LCC offer replacement dash panels for TVRs and from what we're told - at significantly cheaper prices than original replacement parts. Unfortunately their website doesn't mention TVR specificially but drop them a line with your requirements and they'll be happy to help.
The other option - a new one - is the stainless steel dash from Leven Technology. They've chosen a 'check' pattern not dissimilar to the weave of carbon fibre which brightens up and modernises the interior. They have virtually all the Chimaera, Griffith and Cerbera panels available ex-stock.
