    Nuts and Bolts

    I guess I'll post this here

    There is already a reference for sizes here: http://z31.com/wiki/doku.php?id=reso…nuts-and-bolts

    I wanted to add some more here for those looking for it. I recently pulled the motor and some body parts, so I'l add more as soon as I find the paper that I wrote them down on…

    Body Trim and Accessories:

    84-86 Headlight:
    Metal retainer (holds 6054 headlight in): 4x per headlight, M4x8
    Black trim piece (goes over headlight and fog on each side): 2x per side, M5x8

    That's the page I started ages ago elsewhere, glad to see it was saved… and yes it needs updates

    Flywheel-to-crank M10x1.0 -- I believe 30mm long

    Pressure plate-to-flywheel M8x1.25 -- 20mm long

    Yeah, I got quite tired of:
    "Welcome to Nissan! What Part can I help you find?
    (pulls up diagram and I point to screw)
    Oh that one right there? No, we don't have any in stock. We can order it for you!
    (I ask about size) Oh, no, we don't have that information available.
    How many do you need? Just one? Ok! Well, they are $1.80 each, but you have to order 20."

    I like access to the sizes so I can go to the hardware store up the road and get the screw for $0.05. Like most Z31 owners, I'm not in the best financial shape either!

    R200 pinion nut = M20x1.5 prevailing torque nut

    And someone needs to check the crank pulley bolts to be sure, the one I have is: M12x1.25x80mm and uses a fat washer 35mm OD, 8mm thick
