You're the kind of guy who will spend more on replacement parts than it would have cost to get a brand new device aren't you... With relegendables it is always the top lens that is missing, thus there is a shortage of them and it is very unlikely that they will be sold separately by anyone here. They always sell complete relegendables, or relegendables missing their top lenses. Thus you will have to buy complete relegendables from me or someone else here.
No offense, just giving my observation.
