The PC drive is not a direct plug in replacement.
On some drives you can just get away with swapping the diskchange and ready lines over (plus DS1 & DS0), but it really depends on the PC drive. Some work great, others don't wanna know you.
Look on my website under the floppy conversion section:
http://amiga.serveftp.netI've written a section on modifying an older model Panasonic JU257 as a plug in replacement, plus some additional info.
