What do I do now:(

What size are the supply tubes and what size are the outlets of the stop valves? Are the stop valves compression fit connections?

Do you have angle stops that look like these? Let me know, tom

Or you can do this: Leave angle stop as it is. Buy s.s. braided water supply with one end to fit the existing angle stop and the other end to match the configuration of the faucet supply line. Than, use coupling to connect them.
