I have a used laser collimator but it does not fit snugly in the focuser

What matters is that it fits the same as your EPs, so it should be the same diameter. Securing it with 1 or 2 screws (whichever you have) tightened in the same order as EPs should put it in the right place - assuming it does have a similar closeness of fit to your EPs.
