I've bought many of these copper jaws that are Wilton and 6 inches wide for $30 shipped. i could trim them down for smaller vises, but have yet to do so and they work great. also my paypal barely gets processed and the package arrives at my door 3000 miles away. the sellers are awesome so giving them a big thumbs up too.
Cuda: also just an FYI. when i am cutting, sanding, grinding or whatever on something in the jaws of my vise i usually put a rag over the slide to keep the shavings out of my vises. it is easier to shake a rag off that might take some of your lubrication from your vise than to re grease or oil than to have to do a full cleaning when it gets gummed up with the crud.
Fretters don't change a thing and we'll get used to some of the words you throw at us. also just saw your post and these jaws are maybe an eighth inch thick. they are not flimsy, but the wings will bend down nicely down over your vise to hold them in place.
