UPDATE: Yes it is a TT spring clamp. I was able to find an excellent correct spring clamp locally. Thanks to everybody that responded and helped me out!

(I apologize in advance for the lighting in the pictures. However, I think they convey my issue.)

I'm rebuilding a 26 Roadster. The front spring clamp that was on the car when I got it, is an earlier 2 U-bolt style like what is on my 1914 Touring. See picture below with a test fit.


I found what I thought was the correct spring clamp at a flea market. It even has a threaded hole for the lower rad cover. However, with a test fit, the studs are quite long which makes me think it is for a TT with a thicker spring. In the picture below, when mostly tightened on the spring, the studs at the arrow are a whole nut depth longer and the cotter pin hole is way below the nut (circled). It can't be right.

Is it a TT clamp for a thicker spring?


I'm not too terribly concerned with correctness, but I'm trying to minimize compromises. I suspect I can just cut the studs shorter and drill new cotter pin holes. I'll also have to make sure the threads go far enough. I'll admit though the earlier clamp looks more "substantial" at clamping the spring.

Yes and NOOO…The bottom picture is definitely for a TT - yes. But noooo, don’t cut it down. They’re not as numerous as the T crossmember/spring clamps. I have a half dozen of the later T clamps I’d trade for yours…

I adjusted the 2nd picture to make easier to see

TT clamp, longer studs for the bigger spring pack

TT clamp, longer studs for the bigger spring pack

That TT C.C. front bearing and spring clip, # TT-1164-B uses larger nuts, as thread is 5/8" x 18, same nut as axle nut. Plus, the clip also longer for the taller TT front crossmember.

The '26-'27 clip, # T-3075-C with apron screw hole, thread is 9/16" x 18, same nut used on rear radius rod bolts.
