The faucet I purchased is a Delta with 4inch centerset. The vanity top I am wanting to purchase says predrilled for 8" centers... this is greek to me! Does that help to identify if they will work together or not?
Thx Again!

It means the faucet is not going to fit the vanity top. The faucet water supply and mounting are 4" apart . The holes in the vanity top are 8" apart.
