No tiny... that is just a metal wrapped cable...
I am talking about the "speedo" end of the cable (not the tranny end)...
The back of the gauge is much like a standard speedo except the square end of the cable fits OVER a square piece that comes out of the back/center of the gauge and then the end screws onto the gauge as one normally would...
Jim Carter's differentiates this kind of cable from the others (1937-72) with the "large square end" addendum I mentioned earlier so clearly there were two types... I just happen to be "lucky" enough to have the hard to get type (why am I not shocked?)

Yours sounds like a standard speedo cable... mine is basically one male end at the tranny and the "large square end" at the speedo is female... does that help?
