Recording this for those who may follow.
I believe late Mark IV after chassis 510101 and 610101 and LHD, possibly also late 1-1/2 L, have a tool compartment lid either the same as Mark V or very similar.
The factory had an assembly order so the cars could be built efficiently, and they wouldn’t have any wasted efforts on the assembly line.
This is my version of an assembly order for the tool compartment, which assumes your parts are all restored and ready to go.
- Cut a piece of jute padding 6" x 36" and use a good adhesive to glue it inside the boot lid approximately where the starting crank handle will be located later
- cut a piece of mutocell tar paper or equivalent soundproofing material 20" x 36" and glue it over the jute; the factory used roofing tar.
- assemble the latches and hinges to the tool lid
- install the aluminum trim channel around on the lid, be sure to use short screws and to put in enough carpet tacks. The channel should be opened enough to put in the padded liner easily later on, but not now.
- install the light holder, with a red and a black wire, tape down the wires, and be sure they make good contact and are long enough. A pair of disconnect bullet ends on each where they can be easily accessed is a good idea, and they can be tucked down inside.
- be sure all your threads in your captured nuts are clear, not full of paint
- install the light switch in the boot lid and be sure you have it adjusted for length so the tool lid will push it.
- install the threaded inserts for the hinge screws in the boot lid
- install grommets to protect the wiring in the boot lid entrance and exit holes and in the main body
- push a stiff wire through the grommets that you will use later to pull your red light power wire through.
- paint the lid prop green; my lid prop is riveted together so it can’t be taken apart for later assembly of parts in the lid
- attach the lid prop to the bottom of the plywood tool tray
- install the plywood tool tray in the boot lid
- paint the tool tray screw heads green
- install the lid with 6 screws in the 3 hinges
- attach the prop to the lid with 2 screws
- connect the light wires, black to the switch, and tape the red to the stiff wire, pulling the red through with the stiff wire to the harness inside the body, where there are a pair of red/green wires and a double bullet connector
- cut a slot in the padded liner for the prop, put the padded liner in the lid with a lot of adhesive, and push down the aluminum channel around it to clamp it tight.
- install the light bulb, clear cover and chrome trim ring, and test the light
- close the lid, latch it, and let the glue dry
