    Rear Carrier Mounting Bracket?

    Hoping to tap into the vast mechanical knowledge here, with a very simple question. I'm in the process of putting together a commuting ride, with parts I've had around for years.
    The bike is a ~ 1976 Motobecane Mirage that is in great shape. I bought an aluminum Blackburn rear rack ~ 10 yrs ago, and it came with 'mounting hardware', which consists of two sets of allen-head bolts and their nuts. The bottom carrier arms fit fine on the 'mating loops' at the rear dropouts, but where and how the front ('seat-tube') arms are to be attached is a mystery to me. There are no 'mating loops' that could be used to attach the forward part of the carrier, on the bike frame itself; the 'mounting hardware' bracket must be for some configuration present on a newer bike, but there is no way it can be used with an older set-up. I've been checking bikes with the 'old-school' Blackburn racks, on the street, just to see how they are mounted, and they all seem to involve some convoluted set-up using either a seat-tube clamp, or some 'sandwhich' type mount, all involving a lot of metal.
    I've searched the net for these brackets, and anything simpler, without success.
    Can anyone set me straight on a manufacturer who supplies what should be a simple bracket for a simple problem?
    Thanks, BJK

    So you are missing the rack braze-ons on the seat stays? (above the rear brake)

    you can use something like this:

    Brilliant minds think alike...and fast: thanks to Vulpes and Stokessd for getting me exactly what I need: simple, no extra unnecessary metal (you would'nt believe some of the insanity-bought from a bike store no doubt-that I've seen for this purpose).
    These clamps should do the trick.

    To answer Vulpes: yes, both my Motobecane Mirage (~ 1978), and Raleigh Supercourse (1981) have no braze-ons to anchor a rack. I'm assuming if I purchased (then or now) a frame specifically built for touring, that I'd see this feature?

    Can't really recall the last time I saw any 'vintage lightweight' with such anchors, then again, the above frames have no braze-ons for water bottle cages either. The Supercourse (which I bought new then), was marketed as an 'entry-level' racing bike, believe it or not.

    Thanks for the quick solution, BJK
