upgrading M-504 speaker binding posts



I've seen a couple of ebay listings for the old M-504 dual mono amp that has upgraded/superior speaker binding posts to what originally came out with on these units (the old ones only allow for stripped/bare wire - cheese!!)

Here's an ebay link to some binding posts:

PKG10,5 WAY AMPS SPEAKER BOX TERMINAL BINDING POSTS,RBD - eBay (item 290270946657 end time Jun-24-09 19:14:00 PDT)

Here's an ebay link to an M-504 that has upgraded posts:

ONKYO INTEGRA M-504 POWER AMPLIFIER WITH UPGRADES - eBay (item 260406878298 end time May-14-09 17:28:15 PDT)

What I would like to know is how the upgrade would be done. The guy selling the amp said it isn't that hard, but he wouldn't expain details.

Thanks for any help.!
