just a quick browse through the TR site and came across this which is a TR2/3 steering tie rod.
Also this one too.
What caught my eye was:
A. the welds on the straight section. I know Peerli/Warwick's had a weld either end. I put this down to both having a wider track than TR's but didn't know ST did the same!
B. it looks to me as though this section is tubular and not a solid bar as there is a hole in both items?
I know the Peerless item also has a second "drop" in its shape to. I guess these TR parts could be non standard? but both of them? although they seem to advertised by the same owner.
