There are some incorrect fuse charts out there - having a fuse in an "unused" slot does no harm, so you might try filling some empty spaces.

Dont know a tq value, but hard to get a tq wrench in there anyway. problem is that a 24mm wrench is pretty long, so its easy to get too much tq on it. I would just 'nip' it up gently (hold wrench as close to the m/cyl as possible), and then check it for leaks (somebody else pushing the pedal, with engine running for boost), and only tighten a little if there is a leak. IIRC the threads are tapered, so thats why the casting breaks if you overtighten. Dont ever recall using teflon on this sort of case.

it looks like I need to also change the brake pressure switches on my '81. I have 24mm crow's foot and two new switches. The one in the back looks very difficult to access -- any tips on this project from those that have done it before?
if I'm careful, can I replace these switches without having to bleed the system?

Yes, you can w/out bleeding. Block reservoir breather with gladwrap under the cap. remove wiring, undo and refit 1 switch at a time, not too tightly. remove gladwrap, top up fluid, kick pedal up/down for a minute or two, preferably leave to sit overnight to allow air bubble to rise through reservoir, should come up ok. Worked for me.

Be very careful installing the switches. If you hear a little "dink" and it feels like you've stripped the threads, you've just bought a new master cylinder!
The MC is a rather brittle cast iron. If you apply too much torque it is very easy to shear off the threaded boss. Don't ask me how I know....
