They look like standard Austin 7 track rod ends, all cleaned up and shiny.
I don't know anyone makes them new, but there should be second hand ones around.

Yup. and bush kits cheap too from all outlets.
I like that shiny steering arm! I presume that would be a good safely mod on an original arm, to check easily for incipient damage?
Is that a polished and sculpted front spring leaf?!

Not sure how the two track rod ends attach to the tubular axle but the shocker link looks very fancy !

Seeing the topic has more or less been raised, chrome plating is reckoned to have a deleterious to very deleterious effect on fatigue life, so best avoided for steering arms and the like in high use cars.
Many track rod ends are expanded. Can still use by making oversize pins. Old valve stems promising.
What does grese nipple on the tubular axle serve? Do the radius rods meet in the usual place?

thanks i found some from tony betts
got those too-thanks
and yes it is a polished sculpted item
cheers
its nickle if that makes any difference bob?
the rods meet on the side of the chassis rail
its not my car but i guess the grease nipple goes into the bolt holding the track rod end pin
they bolt through an eye in a large pin that runs through the axle and bolts at the front

Not the bolt, a tubular axle is articulated and as a result this needs to be greased, the articulation is there because radius arms are attached to the sides of the chassis not a central pivot, if the axle was not articulated it would act as an anti roll bar and the car would handle badly.

HI All,
Looking At the photo the track rod bolt is able to rotate hence the grease nipple, as the rod end only has one pivot pin Vertical.
That end of axle is welded solid so any rotational movement must be at the other end.
As Ian has said the axle must have rotational movement and usually not at the point were the track rods meet.

Colin I take your point but most modern reproductions such as the one depicted have a fine thread in the spigot onto which the track rods attach rather than the original more complicated design.

On the likes of dirt track cars twin tubes are used partly to accommodate some twist. A ball joint at the rear end. The split pin suggests that might be free to turn in axle? In view of the castor tweek method for early Sevens would be a curious arrangement.
Despite the through bolt, is there an inner tube carrying other stub axle? Hence the nipple?
