Need advice for MSD parts..
 

Morning, I need to know if this is the right part number at summit for the MSD Ignition box 6AL: MSD-6420

I seemed to have misplace my summit magazine, and I was browsing online but I'm not so sure now. This is for a 95 z28.

Also, is this the right part number for MSD 8.5 mm wires? MSD-32149

There lots and lots of different part numbers for that and I'm not quite sure which one is the correct one. Another quick one, for the MSD box, is the box itself all I need to install it and make it work? Are there any other special parts/items that I need to buy to make this box functional? I hope someone can answer these n00b questions for me. Thanks in advance..

Oh, another thing, this will be my first time ever ordering anything from summit. I'm curious, do they charge tax at all when you buy stuff?
