1970 Dart - Single-Wire Alternator Conversion

Gents -

I've scoured through these threads and am not finding one with a similar setup as I have (very likely could be a thread already like this but am not finding it, sorry if so)

Going from factory alternator to this alternator as I have a number of electrical mods and fried my alternator and my fusible link a few months back and I have a few questions...

1. I bought this 6GA wire to run from my alternator to my battery and want to install a fuse - what size do you guys recommend?

2. I want to eliminate the ammeter, what is the simplest way to do this? I tried looking at the MAD Electrical way and confused the hell out of myself... Is there a simpler way? If anyone is in the metro Denver area that would like to do this for me I would gladly pay them

3. I have an MSD 6AL ignition, does this throw anything off in any way?

Thanks in advance for any input! Again, if anyone around the Denver Metro area would like to do this for me, I'd gladly pay as I don't feel 100% comfortable with electrical.
