Does anyone know what all the complete tool kit consists of? That's the tool box in the right rear of the 740 wagon. I have a couple of open end wrenches, a spark plug socket, pry bar for turning this socket and removing hubcaps, and hex socket screwdriver with 4 bits inside the handle. Looks like there should be 5 or 6 bits because the most common torx bit is missing. It looks like there are spaces for another 4 or so items.

That's about everything. There were sometimes a pair of thin cloth gloves and a shop rag, at least, I've often found those items in tool kits that appeared to be untouched. I'm not sure how many bits there are supposed to be in the screwdriver handle. They varied from year to year, depending, in part, on whether the car has Torx head screws or not. The empty spaces are for tools specific to turbos or V6s, so if yours isn't one of those, there's not supposed to be anything there. If the car has power seats, there should be a small crank handle for operating them manually.

I didn't mention the cotton gloves because I thought they were put in there by a previous owner. The space where the tubular double ended socket is also shows evidence of a long L-shaped bar that would pass through it, which is missing. Perhaps that's to turn the socket, not the hub cap pry bar, which fits diagonally across the case. Also, across the bottom of the case where the socket is, it says "ONLY B28 AND 4-CYL TURBO" and I don't know if that means a specific tool would go there or if that's what this whole kit is for. Looks like I'm missing another screwdriver and something tubular that goes in the top LH corner of the case.

I've seen those gloves often enough to be fairly sure they are part of the kit. I think what goes in the "ONLY B28 AND 4-CYL TURBO" slot is a longer tubular spark plug/lug wrench, and those cars don't get the regular one. Its handle might be the mysterious L-shaped bar, or maybe that's the crank for the power seats, and the turbo plug wrench takes the same handle as the regular one.

Out of curiosity, I just got out my 88-90 740 parts book, which shows the box itself, in the full range of colors, and for contents it shows two wrenches 10 x 11 and 12 x 13 mm, the tubular wrench, in two types, regular and turbo, its handle (the pry bar) and a reversible screwdriver (which, in my experience, is usually light blue in color, with straight on one end and #2 Philips on the other, and is only found in cars up to 89. There is no mention of the red handled one with a white cap and interchangeable bits which is standard for 90 and later. (I will check the ones I have some time in the next couple of days and try to determine exactly which bits they are supposed to have---I have a couple of sedan tool rolls that look like the day they were made) There is also the crank handle for the power seats, which has a metal crank handle, a flexible shaft, and a solid tip that engages the seat mechanism. Finally, there is an item I have NEVER seen before, and suspect was not included in US spec cars---a single ended open end wrench, 24.8 mm, presumably for the oil drain plug.

Ah, now that's something that I don't have in my kit! Maybe the space for the mysterious tubular item in the top LH corner of the box is for such a socket. When I changed the oil on my wagon recently, I was amazed that I needed a 1" wrench for the drain plug. A really odd size.

Yes, except that 1 inch = 25.4 mm, not 24.8mm.

The FAQ says use a 1" socket or wrench for the drain plug and I find it works fine, just a little sloppy. Maybe a 25mm socket or wrench would be better, but I don't have one. If a 24.8mm wrench is a perfect fit, it likely wouldn't work after the drain plug has been burred from years of using 1" tools, not to mention (ugh) adjustable wrenches.
