Can anyone say what year or years this drag link was used??

Not a tie rod, it's a drag link. Probably before 1913 but the rod should be threaded at the column end,
20 tpi in 1909,10 and early 11 with the one piece spindles
13 threads per inch late 11 and 12

It might be a transition between 12 and 13. Who knows?

I agree!

I meant to say drag link. BOTH ends are exactly the same. I have a second one of these as well and you can see a rivet in the cast end.

Length is another way to identify them

Check these links from the old forum

I looked up all the lengths I can find.

early cars till 9/19/14 30.687 (30-11/16)

9/19/14 till 10/19/14 30.687 (30-11/16) to 30.750 (30-3/4) A tolerance for manufacturing purposes is the reason for two measurements

10/19/14 till 10/2/17 31.062 to 31.125

10/2/17 till 5/19/19 30.938 to 31.062

5/19/19 till start of Improved Models (Aug 1925) 30.312 to 30.438

Start of Improved Models (Aug 1925) till 10/7/25 31.125 to 31.250

10/7/25 till end of production 30.812 to 30.875

These measurements are taken from the online encyclopedia, service bulletins, and a few other places I can not remember right now. It may not be all the lengths but it is all I have for now. Maybe this will help and not confuse things worse. I just about have the next thread ready for discussing the steering columns (I still need a couple days to work on it). I think the drag links have been discussed fairly well. Thanks again, for everyone's input

The one with rivit is 13-14 and possibly to 17

THANKS ALL!!
