Hello does anyone know what other vehicle might be compatible to my 2004 s40i. I need a hood, bumper and radiator support upper bracket.

 

Even though there are some other volvos w similar design and parts I would stick to s40 bits for your car from other s40s there's tonnes of s40s in breakers yards these days I got 3 engine sensors for mine today for like 20 quid s40 not being made at the moment too so plenty of junkyard filling up with them

 

I believe that the other variants (V50, C30, and C70) all share the same front end components, but as James said above, the non-S40 variants are rare enough that you're probably going to find five S40s for ever "other option" in the boneyards, so it's hardly worth the effort checking compatibility unless your local boneyard only has one non-S40 donor candidate.
