Track rod end
Hi,
Any one familiar with Fiat coupe's - do you know if there is a track rod end that will fit the bottom ball joint on the front hubs?
Its a tapered type with a bolt that clamps around it.

as that is the ball joint that takes the weight of the car (the upper just holds the wheel upright) I'd personally just use a balljoint for that
rather than a trackrod end as they tend to be more robust, most can be quite easily bolted onto lower wishbones with a welded on plate adaptor

That doesn't make sence.
Either, it's a streight pin (with a groove around it) and a clamp bolt through the upright.
Or, a tapper pin with a nut on the end of the pin pulling the tapper into the upright.
If it's the first, there won't be a track rod end that'll do.

The Fiat Coupe bottom balljoint is neither tapered, nor straight. It's an odd looking stepped pin, and it's held in with a pinch bolt, at
least it was on my 20VT and I changed them twice during my ownership.
The bottom balljoint does not support the weight of the car, since it uses a McPherson strut, so the balljoint sees primarily shear forces from
braking, accelerating and corning, and some lower pull out loads from the anti-roll bar. I have never seen a track rod with the same style of stepped
fitting before though.

Thanks MikeRJ, should have asked you. 
I'm using 20VT hubs in my midi and want a ball joint to suit. I was thinking a track rod end as it would have a threaded part to screw into my
wishbone. By the way, I inverted my hub, so the macpherson part is at the bottom if you follow me.
Not sure how to modify that then.....
Should I just stick a bolt through it and attach a rose joint??

I found that the ford Escort and fiesta bottom ball joint fits the fiat coupe hubs!
