First breakdown

[Ditch]

Halfords can be useless with this kind of thing. Most motor factors will have a device or scale for measuring belts even when they are broken. When you get a replacement let us know the size so we can use it for future reference.

Part no 6469mc avx13 x 975la is the belt that fits mine but I've got the andoria engine with a nonstandard alternator on a fabricated fitting
