Oh man thanks guys!!! Loving this forum, and the old macs! 
I will look for the part and get to work..
on another note, I am still trying to get this external drive to boot on the plus, it worked a few times, then no more.
The drive mounts when I start from a floppy, but it will not boot from the drive. Is it possible that the CMS external drive isnt terminated? It has a set of 8 switches on the back 1-8 with on and off positions. I am assuming this is the SCSI selector not the termination. Any thoughts on how to get the plus to boot directly from the external HDD??
