I came across this site last week while on Google Images looking for something else. A few of them may qualify for the Land Rovers That Suck thread, but at least the information is pretty cool...like the first RRC 4 door conversion examples.
FLM Panelcraft Ltd, Battersea, London, UK
Probably FLM Panelcraft was the first company to offer a 4 door conversion available in 1974
In 1972 Rover in Solihull had the first ever 4 door Range Rover prototype developed, but as the British Leyland was in completely lack of sufficient finance resources and the production of the original 2 door Range Rover could not cover the highly increased demand, any further development were abandoned.
However, a demand for 4 door conversion of the Range Rover were increasing, especially from the wealthy oil states of the Middle East. Conversion company FLM Panelcraft developed and offered a
4 door conversion as early as 1974. This conversion became approved by Land-Rover and FLM Panelcraft were recommended in the Range Rover materials for 4 door conversions in the 70's.
A year later Wood & Pickett Ltd also developed a 4 door conversion. Both companies used a equivalent solution for the rear doors; narrow the length of the front doors, shorten the front door and
at rear a cut out in relation to the profile of the wheel arches. Use of the same door pull arrangement This Spanish FLM Panelcraft conversion were sold earlier in 2011
as on the front doors, but narrowed. Maybe the most obvious on these early conversions;
these early conversions; the use of sliding windows and not winding window.
Soon after the FLM Panelcraft 4 door conversion were available with ease of access to the rear seat,
it was a raising demand for more legroom for the rear passengers. FLM Panelcaft made use of 10"
frame extension converted by Spencer Abbott Ltd, the same company that supplied 10" extended
Range Rover variants for the anbulance converters like Stringer Wadham, Herbert Lomas, Pilcher-Greene. This longer wheelbase gave sufficient space for the rear passengers, and allowed FLM Panelcraft to develop longer rear doors. These longer rear doors had a solution with windable window so the whole window could be winded fully down.
At the rear of the rear door was a quarter light window that could be opened for fresh air ventilation and
at the front end of the rear door a fixed window piece to give enough space for the windable glass.
Outside the release opening handle had the same solution as the original 100" 4 door conversion. Inside FLM Panelcraft made use of chopped door armrest and door handles from the original 2 door
Range Rover. Also inside vinyl panels looked very similar to the original 2 door inserts.
FLM Panelcraft 4 door conversion could be delivered with Webasto full size sunroof, air condition, double frontlight, winches, spotlights, special paintwork, hunting seats and other equipments.
