Welcome on the forum. You give me the right words.

A Fulvia when in order has equal to or better handling than most modern cars. The speed of the Fulvia is not in the muscles but in the bones. The Fulvia is basically unstable like homo sapiens and fighter jets. Computers are used to turn the instability into agility and speed. I am preparing a posting in a new thread on this subject.

The steering problem you describe is symptomatic. One of the many unsolved problems. You don't say if the play is dynamic (when driving) or static (car stationary). If static the steering box should be in the centre position, spokes of steering wheel horizontal, wheels straight when checking the play. At the extremes the play is about 10 mm more. The book says 10 mm max (in the centre). We achieve usually 1 mm. Adjustment to 0 mm is possible but not wise. It may damage the worm or the roller when temperature changes. If you really want the sharpest possible steering it is a process. There are plenty of rally roads here in the border region between Holland and Belgium. With a good number of traffic bumps and roads suddenly changing to cobblestones or loose sand or mud. We do test drives there. The owner drives and I navigate and watch his muscles and bones when circumstances suddenly change. When the job is done properly neither the car nor the driver will give a flinch and keep an awesome speed.

The attitude, caster and camber angles etc have to be correct. Subframe rubbers ok. Subframe mounts ok. Some cars have different wishbones left and right. Replacing the silent blocs without the proper tools is difficult. A previous owner may have swapped a wishbone with a donor car. We measure the wishbones. As it happens the car we just started restoration on had two different lower wishbones.

If it is a series 1 Fulvia the canvas Hardy disc may be coming apart. This disc is the connection between steering shaft and steering box. It consists of 5 layers canvas with 4 pieces 90 degree segments of spring steel sandwiched around the centre layer. By now the steel has rusted away on all Hardy discs. If so the canvas layers start to separate. Imitation Hardy discs do not have the steel segments. which results in a lot of play right from new and infinite play (torn in two) after some months. It is apparently not against the law to sell these discs.
The Mercedes discs fit but they are no longer available and they are too hard. They don't have the subtlety of the original Lancia discs. We make our own discs and use natural canvas with segments of stainless spring steel.

Similar story for the conversion kits for the wishbone bushes which are on the market. Wrong dimensions. Wrong thread. Wrong length of the thread. We make our own.

Those are just a few examples. We have tripled our capacity for bodywork on Fulvia's over the last year. Later today or tomorrow I will post some pictures of the car we are starting on on station 3. The present owner bought it recently, restored and all and brought it to us for inspection. We became more suspicious everywhere we looked and finally decided to strip the car and put it in an oven without oxygen to vaporize all organic material such as paint, filler and wax. Terrible. Botch job. Even worse than not having done anything. I was suspicious if the car was straight. We already correct it on two axes. We are now building a special jig to correct old accident damage at the rear.

The subframe also a total botch job squared. We do have a jig to repair subframes. Does not work on this one. We have to build another one.

This is car number 8 that came in over the last 12 months which was recently bought (most in Italy) in supposedly good condition but in reality a total wreck underneath. My standard is that a car must be safe enough to allow my daughter to drive it. That has nothing to do with my daughter's driving capabilities but everything with the car. Well, these 8 I would not have dared drive myself.
