not a direct drop-in, no.
the fender "boron" lightweight keys pretty much cover the old holes, just requiring a little drilling for the new tabs that go into the back of the neck.
they work great on
my '96 P bass, which is nice and lightweight, and would be neck-heavy with the stock boat-anchor keys.
the thing with these is to run a bit of loctite into the little tensioning screw that holds the knob in place. otherwise, that little screw (and its impossible to replace surrounding bushing) come unscrewed and fall out.
