(8) Lift the whole assembly of Carriers, Sets, No. 23 (this is after the Wireless, PSU and Control Box are installed) by means of the carrying handles and slide into position on the Mountings, Carriers, No.1. Fasten the Carriers, Sets, No. 23 securely by pushing up the spring clips at the front left and right ends of the Carrier.
Seems perhaps the Mountings holes were predrilled in the wireless table by Wilson Truck Bodies, or whoever built the tables. Life was so much easier then.

On that basis, I'd agree that the table tops were pre-drilled as part of the contract for whichever set the truck was intended to have installed. (WS19 or WS52 would have been options, possibly with the WS19 (Canadian) HP (though I don't think that ever went into service: according to Louis Meulstee in WftW Volume 2 the Canadian Army Overseas used the British RF Amplifier No.2 due to problems (weight, power consumption, spurious emissions) with the Canadian WS19HP in user trials).
Later use of the vehicle with other sets would have added extra holes or possibly led to the replacement of the tabletop with a new piece of plywood to give a smooth surface with on awkward holes.
