Since the spool is all metal i would say just use some threadlock on them and they should be okay, but like I said i'd be more worried about your cvds busting. When you turn the outside wheel wants to turn faster than the insdie one since it has to travel further, but with no diff the inside wheel will slip & skid on the tarmac, which is wheel the trouble starts if you have grippy tires. Try it and see, but if that does happen, just go back to a rear diff setup with alloy cup and 3mm screws.
