Kaypro 4/84 questions

I recently acquired a Kaypro 4/84 and I'm in the process of cleaning it up and getting it happy. There are a couple of problems with it that maybe someone can shed some light on: * one of the keyboard latches is broken. Anyone know a good substitute and/or workaround? I don't care so much about it, but it'd be nice to be able to lug it into the kitchen and carry something else at the same time :) * They keyboard cable is missing, but I substituted a keyboard cable found online says that using a phone cord causes dropped characters due to the smaller wire gauge, so I'm hoping that this cable will be sturdy enough. * There is a screw in the 2nd floppy drive opening. I've tried removing the drive sled (via the screws on the bottom), but alas it seems like the drives have to come out of the front individually. The screws are pretty solidly inserted and I cannot get them loose without stripping them. I'm not able to get to the inner ones easily without removing the motherboard and the monitor. Is it possible to take the bezel off of the drive and then slide the cage backward and then out? The drives are the shugart ones. * I'd like to replace the 2nd drive with a 3.5" floppy. I've found a Sony HD drive along with a power and plug converter. Knowing that PCs use a twisted cable scheme, what things should I be aware of when cabling in this new drive? Will it be supported in some manner by the software? Its not a big deal if it turns out to be a 360K 3.5" floppy, as long as its readable by my linux box.
