Here are 2 x close-ups from the 1543X2 section of the album showing the configuration of the left side of the transmission showing the tire pump (note lack of vertical control rod as would be fitted to a CMP), and speedometer adaptor (showing the connection to the rear axle shifter).

I have also included an illustration from CC60L-HB1 of the same area to assist in identifying parts.

While the 4 x factory photos of the 1533X2 have been shared numerous times, in the subsequent posts, I will provide a bunch of close-up images that may assist in ironing out some of the details of these vehicles.

Wow, Colin - just wow!

That's is brilliant. Thank you so much Colin.

From my research most LRDG 1533X2 trucks had the twin CMP seat arrangement. This required a riser plate on the fuel tank to give the CMP seats a horizontal surface to bolt onto. The original fuel tank protector strip slopes down towards the rear to accommodate the bench seat which were the standard fit on pre war Chevrolet trucks. It would make sense to use an existing riser panel for this, instead of making one specifically for just 200 trucks. I've been trying to find the cover plate and think I may have found it, or at least got considerably closer. The attached photos show close ups of the seats mounted on a factory fresh 1533X2 provided by Colin Alford on the main LRDG 1533x2 page. The last photos shows fuel tank cover plates from 2 different 1942 M6 Chevrolet Bomb Service trucks. I believe (hope) that they are the same plate on the M6 and the 1533X2, although on the 1533X2 it looks like they trimmed the edges back, which gave more room for the Lee Enfield rifles to be stowed beside the seats and it doesn't have the 4 protruding bolt housings on the front edge, using just nuts and bolts to secure the panel to the fuel tank protector. In the 1533X2 photos you can see an additional plate attached between the seats and fuel tank riser panel.
I've since found that production of the M6 Bomb Service truck started in late 1942, so the 1533X2 had the seat riser before the M6 existed. That means that GM/Chevrolet designed one for the 1533X2 and then used it on the M6, or they anticipated the need for a riser panel on a series of potential trucks and it was then available for the 1533X2 once the bench seats ran out.
Any comments/ additional information or corrections welcome!

The PTO Compressor seems to have various air intake options. In the attached montage you can see illustrations of cylindrical and 'Kidney' shaped filters as well as simple inverted 'V' shaped inlets. Has anyone got any photos of the filters or have any knowledge which arrangment would be used in 1942 in North Africa?
