did a search & didnt find a thread that exactly addresses the question i have...

ive been riding with just the stock [platform?] pedals that originally came on the bike [the bike is a mid-80's nishiki sport] & i have been keeping my rpm's down for safety's sake. obviously, this is not the wisest move and i have to make the move to clips.
the reflectors are not screwed into the pedals, but when i looked at the inside there are 2 holes, about an inch or so apart, that i think it might be possible to install clips in. i tried doing some searches online, but not being too familiar with the terminology i wasnt exactly sure what to look for. the closest thing i found to what i assume i could install on these pedals was a set of nashbar clips:

are these the type of clips that can be mounted to stock pedals, or at this point, would it be wiser for me to swap out the pedals entirely? i do eventually want to re-gear the bike, install a new chainring, etc, but not just yet.
also, i know people will make the case, but i'm not really comfortable with the idea of going clipless at this point.
any help?
