    Here are photos with dimensions. Note: horizontal is Not Level - purely pilot error on my part. Let me know if you need other info.

    Thank you. The height and thickness look to be okay, but it appears that your aluminum rad has an overall total width of 16". Is that correct? From what I can see, the ruler is spanning the width from the 2" mark to the 18" mark, which makes it 16".

    Would you mind taking a photo of the right hand side, the thermostat side? I would like to see the mounting lugs on the right hand side of the tank above the thermostat housing, as that is where the plastic intake trunking parts screw on. On your tank there should be threaded stand-offs of some sort welded on. If you look at my first photo you'll see they have threaded brass inserts. Photo below of the intake trunking mounted.



    Thanks,
    Tom

    The stand-offs have threads in the aluminum that are m5-0.8. Since I have much experience in "munging" (technical term) aluminum threads, I have tools (heli-coil & timesert) for making repairs and installing inserts. If one is careful, it may be possible to actually use the aluminum threads, but torque values should be low and a dab of anti-seize might be helpful.

    The width seems to be a "smidge" less than 18 inches. Paralax (and photographer error) makes this difficult to accurately assess.

    Forgot one image. This shows all three threaded mounting locations -

    You know, this might actually fit my bike with no problems at all. One more thing regarding those threaded mounts. The one at the bottom by the thermostat housing sticks out farther than the two at the top, correct? And the two at the top are on the same plane?

    Cheers,
    Tom

    Yes, this is correct.
