Vauxhall Cavalier Sill Replacement Parts

No — the Cavalier Mk2 (1981–1988) and Mk3 (1988–1995) are completely different platforms with different body structures, so the sill pressing from one will not fit the other. Always confirm the generation of the donor car with the breaker before ordering.

Yes, body style is the most important question to get right. The Cavalier Mk3 was offered as a saloon, hatchback, and estate, and the sill pressings differ between these body styles, so a sill from a saloon will not necessarily suit a hatchback or estate. Tell the breaker your exact body style alongside your registration.

No — trim level does not affect which sill fits, so an L-spec sill and a CDX sill from the same generation and body style are the same pressing. Bear in mind that colour and any body-coloured or rubbing-strip finishes may differ between trim levels, so discuss the cosmetic condition with the breaker.

Both years fall within the Mk3 generation (1988–1995), so they share the same basic platform, but mid-generation pressing changes can occur and cannot be ruled out. Confirm fitment against your exact registration with the breaker before purchasing.

Yes, every Cavalier has structural sills running along the underside of the body between the front and rear wheel arches — they are a standard part of the bodyshell on all variants regardless of engine or trim. When contacting a breaker, tell them your generation (Mk2 or Mk3), body style (saloon, hatchback, or estate), and whether you need the nearside (NS, left) or offside (OS, right) sill.

The Cavalier Mk3 shares its platform with various Opel-badged equivalents sold in Europe, and sills may well interchange, but panel differences between same-platform variants sold under different names is something you should confirm directly with the breaker against your registration rather than assume.
