I can't remember who, but someone ask what was in the B7100 tool kit that came with the tractor. Here is a picture of what came in the tool box of my 1979 B7100. The second picture is a closeup of the end wrenches so you can see the sizes.
300zx, that is neat. I wonder if the thought was to carry extra injectors and glow plugs for the "socket" tips. I guess you could field clean those in a pinch?
I am assuming that is what those are for, they don't look to be the size or large enough for the lug bolts? Probably showing my ignorance here....
