I’ve always just had well planed bare wood, lining vice faces is a relatively modern fad. How tight do you need to squeeze a piece of work? If you are planing it, it is probably small or it would be against a stop on top of the bench so doesn’t need to be held that tight, if you are cutting mortises then again it should be on the top. Sawing? Either on a knee height trestle or against a saw hook on the bench top.
It’s very rare that I need to exert much pressure in the vice.
So there you go I think I’ve saved you the time and expense of fitting it lol.
