What should I replace at the same time?
Where labor overlaps, replace the inner and outer tie-rod ends together on higher-mileage vehicles, then get an alignment.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 1971 Fiat 850 was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 1971 Fiat 850?
First match the engine — each row shows which engine(s) the part fits. Then flush old power-steering fluid when replacing a pump or rack — grit in the old fluid is the number-one cause of repeat failure. The notes column carries position and trim qualifiers where they apply.
