Oh yeah, they'll fit - I know a few people who've done the change. The plastic can look neater than the ally when it oxidises, and the ally ones are a bit vulnerable to cracking if over-tightened. I could post some over to you if you are stuck, or pop over if you are somewhere reasonably near - I'm based in the Burnley area, with my unit in Rossendale. From memory the only issues are connecting the breather pipes and ensuring the earths are properly connected. If you source one elsewhere, ensure that you get both parts of the cover - the black base and the silver top, and that you've got a decent gasket for the base.
