    Another of the problems with these is size. over the years I've bought these and found that even though they came from reputable Norton sellers the vary in width quite a bit. I have a brand new set I will not use because they are 1/8 to 3/16 thinner than the ones I like to use that allow my brackets to come together with no stress. I like the idea of ones that will be " hopefully " longer lasting if not permanent. My only criticism of the ones I saw on your parts page Matt is minor, I personally don't care for all the shinny bling so I want mine black. I think I will order a set & just put some black shrink wrap over the coils... Glenn T.S.

    Peel had spring support for her long Dustall mega, required one longer more vertical spring for vertical bounce and another shorter angled helper to tame springing outward. Next Peels gets a hybrid redesign but for plain Trixie i keep spare speedo drive, tires, chain, oil and rubber mounts on hand though I waist all mine now so do not last quite as long but nicer to me and Cdo while they do.

    For the benefit of our cousins out in the former colonies who suffer from a lack of education in proper English ...

    'Bollocks' in this instance probably translates as 'Sick' or at the very least 'Awsome' :mrgreen:

    Yes, that took me some research time the first time I saw it (in these pages, in fact). "Sick" never did it for me; I prefer to see it in my mind's eye as "Bitchin!"

    Oh gosh, turns out they are the dangling bits of the cart pulling cattle (and not the cattle themselves)!
    I don't know if I need more of them on my bike.

    The top compliment is "gnarly."

    Okay, back to the subject at hand. I received my 60A durometer mounts from McMaster-Carr yesterday (http://www.mcmaster.com/#4403k511/=xjumj4), and found that 60A might be a bit stiffer than stock. I did note that the point where the Iso's take over moved up about 300-400 rpm. It's hard to know for sure, since the old mounts are, in fact, over forty years old, and one was heavily oil soaked (imagine that), but overall, they were in surprizingly good condition. They were also marker "Metzeler", echoing 79x100's and Torontonian's observation about the better mounts. An initial check by burying my thumbnail into the rubber seemed to be pretty close to the stock units.
    Dimensionally, they are spot-on, aleviating gtsun's concern of incorrect size. That being said, the thread pitch is coarse, requiring new hardware. Not a bad idea to change it out, anyway.

    Here's a new item (can you guess which one it is?) flanked by both the "good" and the oil-soaked used mounts. The picture makes the mounts appear different in length, but they're within .020" (not counting the oil-soaked dog).[​IMG]

    Note that the stud is about 3/16" longer. This caused clearance issues in only one location, and was as simple as hack-sawing off a couple of threads. I probably could have gotten away with leaving it as is, but the iso's might allow enough movement to score the swingarm. Here it is before trimming:[​IMG]

    'Found this while disassembling the right side. Dodged a bullet there! [​IMG]

    That, and the oil-soaked unit, might be what caused the change in vibration noted with the new mounts. It's hard to say without having the "proper" mounts to use as comparison.

    Before and after on the right-hand side:[​IMG][​IMG]

    The orange doesn't look as bad as you might think, since it's not fluorescent. I'm just thankful they're not fluorescent green! We leave on our trek next Friday, so time will tell.

    Those bracket plates with an offset... did you custom make them?

    Nope, factory. This is an Interstate variant, if that has anything to do with it. The left side is straight/flat. I've always wondered about that myself, but the mufflers have always slid right on without any binding/misalignment noted.

    Dirtbags! Let me know if you want some. I don't mind sending up to my Canadian brothers.

    No, they wont ship anywhere out of the US and they blackballed me for asking.

    "Due to the complexity of U.S. export regulations, McMaster-Carr accepts international orders only from our established customers. This decision also applies to orders shipping within the United States, because it is based on the final destination of the items. We cannot accept this order or future orders."

    I can't blame them for that. Not worth the hassle for a few Canadians. :)
