Perhaps the documentation you require is all in the SVA manual.
This manual gives all the specifications required to register the car on the road in the UK. (This is higher than MOT and more stringent)
Vehicle testing manuals and guides
At the bottom of thepage it gives the price at £37.
That said a GT40 tends to fail on a few items due to it's height.
Headlights are too low so suspension needs to be increased to maximum for the test,
Indicators on the front are too low so need to have additional ones fitted higher (normally a small motor cycle type near the headlight
The rear clip (boot) has to be stopped from opening to full height or the tail lights and emergency hazard lights cannot be seen.
Reversing and rear Fog lighs need fitting above minimum height.
Lights must bear the required E marks
The emissions are based ont he age of the engine - and proof of engine age can normally eb obtained.
Brakes can have a bias bar fitted but at the test the bar must be locked in position with something like roll pins - front wheels must lock under braking before the reat. Brakes are tested for efficiency with and without boosters.
Seatbelt mounting points need to be in a triangulated area of the frame
Seatbelts must have the necessary E markings
Windscreen must have an E mark
Then there are numerous tests for sharp edges.
The manual is very detailed and about 140pages long.
Or if you have specific areas in question I'm sure a few pages could be faxed over!
