Line6 4x4 (DL4, MM4, DM4, FM4) Battery Contact Replacements

Does anyone have a lead on replacement battery contacts for the Line6 'big box' effects pedals? These seem to be prone to corrosion and I have several that could use a fresh set of contacts.

Not sure where to buy them but you may be able to salvage some from something else. For years I have been saving them from old remotes or anything else I'm throwing out.
