How to put maple neck back on Fender (Squier) Pro Tone Strat?

Hi, I ordered a Squier Pro Tone Strat from ebay and the fellow wants to ship it with the neck off for safety reasons. Has me worried as I've never put a neck on a guitar before and am wondering about alignment. I have set up many guitars and do a fairly good job of it. Is it really just 4 screws and falls into place? I have my doubts but that's what he says. Thanks for any info.
