thanks flammenwurfer, the cable straps are Leather and Glove Snaps. You need a hole Punch and a snap setter to work with the snaps...a snap setting kit is cheap and once you have a kit made up with some snaps and rivets you will find all sorts of uses for it. I get my stuff from Tandy Leather. I set myself up initially with a couple packs of snaps, some rivets and some grommets and they sell a setting kit that does em all for like 15 bux. I think I spent 25 and I've got enough to last me a long time.

Just the other day I used the hole punch and some rivets to fix up the stay bracket on a set of old ESGE fenders. Infinitely useful.
