Fig.1 I would like somone to identify this trunk button for me please. If it is Lancia, what year, model, etc	Fig 2 inside a P400 trunk light. 2 oval chrome screws hold face on light at each end. The glass lens held in by soldered tabs. No marking found on anything! The light is riveted in the trunk thru the far end holes. The trunk light is difficult to see, but works well. Trunk photos will never show it as it is under the forward horizontal edge of the trunk.
Fig.3 P400 trunk light assembled. outside dimensions are - 85mm long x 40mm wide. installed the heigth or depth is 23mm. 11/2008 info from Jürgen Wilms - OKP Parts and Engineering Repro light	Fig.4 P400 panel knobs, holding left and right trunk panels in place. threads are 6 x 1,0 , 19mm round dia, 19mm tall, hard black plastic.

Fig. 7 Trunk hinge. 6mm x 20mm steel strap bent to shape, 6mm weldnut for overtravel bolt, 6mm ID tubing for pivot. The later model S/SV uses "C" channel material for this hinge (probably 2mm material, but 6mm channel). This later C style also has a "tongue" for tripping light switch on left hinge.	Fig.8 Trunk lid prop rod early P400, riveted to body, also clip. Trunk lid prop arm late P400, spring loaded, welded to frame.
Fig. 9 round tube frame trunk lid - a very specific characteristic of a P400. The simple welded tube frame has a flange of flat steel sheet added, which allows the the aluminum skin to be crimped to it.	Fig. 10 CEAM clip on style switch - P400 only There is a very specific location for this clip-on CEAM switch. It mates with a specific trunk frame pad that is added to the forward left edge of the round, tube steel frame of the trunk lid. The picture of #274 below shows the approximate correct location.

2007 March - Trunk lock buttons on Miura built after approximately #98 show the OEM style to be the thin rimmed type as shown on the left columns. The replacement buttons are the more commonly found, thick rim style. The two styles readily replace one another, but the big difference is the lock cylinders are different.
The thin rim style lock OEM Miura trunk cylinder requires a Fiat/Lambo/Ferrari key and matches the doors.
The thick rimmed style trunk lock cylinder requires a Lancia key and requires a third car key (ignition, door, trunk).
The thin rimmed style are extremely prone to corrosion damage because of low grade potmetal in the thin rimmed cylinder and because of the fact that the trunk locks are left in the inward locked position, moisture accumulates in this annular area and remains to corrode all.
The thick rimmed style cylinders are made of brass instead of potmetal and simply survive the environments better. The thick rimmed style are found in period Lancia model automobiles.
This trunk lock is a great check of a Miura example reporting to be unrestored, all original.

Disassembly of trunk lock requires the #12 pin be driven out. The head is peened in a flare. This flare or even end of the pin must be removed prior to driving the the pin thru the assembly to avoid pounding this flared end thru the other pieces. Doing so will enlarge the bore hole and gall damage the other pieces. Even if you remove the entire end of the pin, there will be enough material to reuse the brass pin. Think carefully about appropriate support prior to attempting to drive the pin out or in.
