I think its been done due to the position the steering rack is mounted in the chassis. Not sure what effect it could have on the wheel geometry,
presumably they're meant to be this way and the wishbones are designed to try and correct any geometry changes. Does it handle ok?

If it was a mistake then that's a blinder, if it was deliberate then its even worse. If the upright is upside down you will have -4.5° of KPI
(King Pin Inclination) between the upright and hub. This will cause the opposite of self centreing (self steering?) and no change wishbone geometry
can correct this (its set by the angle between the hub spindle and upright).
Get them turned over (and swapped to the correct side)

Might not be so much of a mistake...check the taper in the steering arm for the track rod end, if the hubs are on reverse the taper must have also
been re-cut for the track rod end to go in from the other side. Otherwise the angle of the steering link would be huge with massive bump steer
problems.
May well be how it was intended.

The track rod end is going in the correct way (as standard it comes up through) so the taper will not have needed to be re-cut. This is just so wrong
though.
By the way Oddified, I went to Uni' in Preston and saw your car around the place a couple of times. As car nerds we always enjoyed seeing it.

In that case, the car must have been designed (or intended at least, designed might be pushing it a bit!) to run them upside down. Flip them over/side
to side and putting the track rods on from underneath would lead to massive bump steer issues without also moving the rack.
I've had my car for many years now, it always gets noticed!

I've been a bit slack at work so we have been looking at what would happen and the main problem is that due to the upside down KPI and standard
castor angle your outside wheel will lift massively on turn in and the whole car will nose dive onto the completely unloaded outside front tyre which
will have no grip and so you will likely some sort of accident.
Unless......... somebody was building a drift car. In which case it would be a crafty way to have front camber of 4.5° and maintain a flat contact
patch on full opposite lock. I'm doubting this is the reason though!

The early F27 used upside down Cortina uprights mounted the wrong way up.
The Cortina was designed with a relatively low king pin inclination and castor angle built into the upright so this was just about OK provided the
designer is prepared to accept a large amount of negative camber.

The previous owner was an absolute idiot. I have cut and removed all of his work. These are just untouched since I got the car

Very strange!
Minor issue given that cock-up but... is there no lock nut on the top joint/wishbone either?

All the posts and pics are visible to me too. Safari on a Mac.
Blast away, but isn't it the same thing whether you get "trail" before the axle line or behind? When it comes to self centering and
stability I mean.
