I've hopefully become involved in 2 LRDG Ford F30 builds within 24 hours, on opposite sides of the World. 
I know quite a bit about LRDG Chevrolet 1533X2s, and have picked up knowledge along the way about the Fords and the modifications that were made to them. One of the trucks will be a Y Patrol Wireless vehicle and the other hasn't yet been narrowed down, but will most likely be a R or T Patrol truck based on where its being built.
I saw Ian Chard last week, a local LRDG historian and son of Harry Chard who was in Y Patrol, and nicked a load of new photos and information which with all my other research and photos I have a good knowledge of what modification are needed.
- 134 1/4" chassis
 
- 3A1 steel body
 
- Chevrolet Axles (Ford axle production  was delayed and so early Ford F30s were fitted with Chevrolet Banjo axles)
 
- Condenser on Drivers side step
 
- Sand mat racks
 
- Sand Channel racks
 
- Rifle clips
 
- Fire extinguishers
 
- Morris truck Aero screens (optional)
 
- Removal of upper bonnet/hood panels
 
- Heat insulation around drivers footwell?
 
- Sun or aero compass mount
 
- 3A1 body moved back 12"/300mm to put Centre of gravity over rear axle and 2 spare wheel racks between cab and body on some trucks.
 
- 10.5 - 16 wheels/ tyres.
 
Wireless truck 
- 2 plywood compartments behind 3A1 RHS fold down side panel for No11 set and Philips 635 receiver.
 
- Aerial post
 
- Windom aerial poles stowed between chassis rails under body
 
What I need to clarify 
- 3A1 dimensions and details
 
- Was a Charging switch panel fitted to the wireless trucks? (feature on 1533X2 trucks)
 
- Was a PTO Compressor fitted to any of the LRDG Ford F30s
 
- Was a heavy duty radiator fitted?
 
- What other modifications are known or possible -heavy duty engine mounts? Uprated fan or air filter?
 
The aim is to make the trucks as accurate as possible using all the latest research and information. I will post any updates and most likely request further information. 
Thanks in advance.
