if you hit a snag, just post or email back.
if you go the wire rout, just make sure it is out of the way of the advance mechanism.
some people LIKE having the more original copper strip. you can make it out of many things and be 'close'.
1, copper or brass foil from a hardware / craft store... cut with construction scissors / tin snips., drill holes at ends.
2, pound a short piece of 3/16 or 1/4 copper water line flat, drill 2 holes for ends.
3, I've even seen one made from a snip of galvanized tin roofing! worked fine! so i left it in place. still running a decade after i found it.
