Yup, just bring the bulkhead with you. You'll want a male threaded to a female slip connector. Make sure the threads fit in the bulkhead and get the right size slip connection for your standpipe.
I think he has a threaded bulkhead and was looking to put threads on a piece of PVC. However I like using slip bulkheads for the standpipe side of overflow drains. Makes it much easier to get the standpipe out if it gets clogged or for general maintenance.
