    Anyone have a source for the slightly curved (convex) speedometer glass?

    And no, I don't want flat glass and have tried glass shops.

    I've never seen curved speedo glass. Must be a feature of the earlier Jeeps.

    I've seen it... it was on the '55 speedo I made into a clock for Duke.
    I have no idea where repros of that glass could be obtained. :?

    The King-Seely speedo used in '55 has the curved glass, not sure if it carried over into the early S-W "white needle" units used in '56-'57.

    Maybe try a clock shop or some related source of such materials. If the diameters are the same as the later flat type maybe an artsy fartsy glass blower could un-flatten a flat piece?

    sammy Coca-Cola?

    seems like a watchglass from a lab supply store may be the ticket? the clock shop sounds good as well

    If the the clock glass doesn't work out try one of the speedometer repair/restoration places.

    Shoot, that clock glass looks too convex. I'll call and ask about the "convexness"

    i learned a new word!

    convexness
    convexnicity?
    convexity?

    Keep us posted. The convexity looks about right, as best I can recall. A quick measurement on the later speedos here at my desk indicate that the 5 1/4 is probably the right size.
    $12 seems like a reasonable price for this glass that would otherwise be made of unobtanium ;)
    I'll have to bookmark this site if the measurements and convexity turn out right... I can use it when I make my "bogus" 55 speedo clocks. :D

    I just bought some 5-1/4". I'll report back with a side-by-side of the "convextivity" of the new vs. original.

    I received the glass from Norkro. First, I ordered 5 1/4" and should have ordered 5 3/8" instead. I was able to make the slightly smaller diameter work with some silicon. Second, the convextivityness is much greater, by about 1/4". It looks fine, and much better than what I had, but still not correct. I'll post some pics when I get a chance.

    Perhaps you could use the glass from a convex mirror and strip the reflectiveness off the back. just something to try if it came down to that

    Here are a few pics. The new glass is too convex, but it still came out nice.

    Convexity is a word. The others aren't AFAIK.

    Jeep Rescue - I hate to tell ya this, but that's a 1956 speedo, not a 1955, and I believe it should have flat glass.

    This is a 1955 CJ5 speedo.

    But I'm on the search for a nice 1956 speedo, and yours is a dandy! Wanna sell it?
