I have a classic-facelift car and I want some new springs.
Want I want to know is, do I have to get springs specific to my model or will any springs do?

I've seen plenty at the breakers yard and on fleabay but they're all for either the bug or blobeye but I don't know if they fit the same.

 

No springs from a Newage will fit the Classic. You'll have to look for springs that are/have come off of a Classic I'm afraid.
