Used Vauxhall Cavalier Rear Cross Member

The Cavalier ran across two main UK generations: the Mk2 (1981–1988) and the Mk3 (1988–1995), and the rear cross member is generation-specific so parts from one will not cross to the other. Within each generation, body style matters enormously — hatchback, saloon, and estate versions each have a different rear structure, so always confirm which body style you have when contacting a breaker. Never assume a part fits simply because the year range overlaps.

1988 is right on the boundary between the Mk2 (ending 1988) and the Mk3 (from 1988 onwards), and some late-1988 cars were already Mk3 models while early ones were still Mk2 — so the year alone tells you very little here. Confirm which generation your car actually is before approaching a breaker, ideally using your registration, and ask the breaker to match it against the same generation and the same body style (hatchback, saloon, or estate). Crossing the Mk2-to-Mk3 boundary is unlikely to work and we would not recommend assuming it does.

Yes, this is the single most important question for this part — the rear cross member is a core structural component and the hatchback, saloon, and estate all have a fundamentally different rear end, meaning parts are not interchangeable between body styles even within the same generation. Always tell the breaker your exact body style alongside the generation, and double-check this against your own car before buying. Fitting the wrong body-style cross member is not a minor mismatch — it is the wrong part.

Trim level makes no difference to the rear cross member — the GL, GLS, CDi, and other Cavalier trim grades all share the same underbody structure within a given generation and body style. You may find cosmetic or minor equipment differences between trim levels when stripping a donor car, but the cross member itself is unaffected by trim. Focus your search on matching generation (Mk2 or Mk3) and body style instead.

No — the estate has a completely different rear body structure to the hatchback, and the cross member is one of the parts that reflects this most directly. Always source from a donor car that matches your own body style exactly, and confirm this with the breaker when you make enquiries. Mixing body styles on structural rear components is not a fitment grey area — they are different parts.

Within the Mk3 (1988–1995) you still need to match body style first — hatchback, saloon, and estate differ structurally at the rear. There is also the possibility of mid-generation pressing changes that could affect whether very early and very late Mk3 parts interchange directly, and this is something you should confirm with the breaker against your registration rather than assume. A good breaker will cross-reference your reg to make sure the donor car is a genuine match.
