Thank you everybody for the advice. I think I'll keep the levers and just replace the cables. The part that keeps me a little nervous, though, is cutting the housings. I do NOT have a Dremel or a grinder of any kind. Perhaps I should head to my local DIY bike kitchen? Any other ideas on cutting the cable/housing?

For future reference, any idea on what brand these levers are, based on that barely recognizable logo? It may help with finding some rubber hoods to slip over the top.

THANK YOU, one and all.
