At the same time, other parts like struts, springs, and coil overs can have varying dimensions and spring rates.
However, you can replace them for the 2000-2005, 2006-2007, 2008-2011, and 2012-2015 models.
For example, Ford Focus SVT has the same spindles for 2002-2004, 2005, and 2006 variants, while for all other variants, you can swap them for 2000-2004, 2005, 2006, and 2013-2014 versions.

4-speed automatic transmission 4F27E compatible with 2.0-liter and 2.3-liter Duratec I4 engines is interchangeable for 2004-2007 variants with same engine variants only due to a difference in their gear ratios.
DPS6 transmission is the same for the 2012-2018 versions. However, the transmission control module (TCM) differs for the 2012-2016 and 2017-2018 models. Therefore, you can swap it within these options only.
