The former is going to be a pain. The latter are findable on eBay. If you
can't find one, drop me a line - I may have one I can spare.

Don't worry about it; BITD we used to run for short periods with the cover
off, to calibrate heads, etc. The air-flow through the pack and out the head
entrance hole will keep the heads clear. I wouldn't run them without the cover
all the time, but for short periods, it will be fine.

The second part is correct, but not the first: BC11 cables are now pretty
much unobtainium.
