Hi

I recently purchased a Univega Gran Rally and thought about adding toe clips. This was when it was discovered that my pedals were installed on the wrong sides. I was told that the threading is possibly ruined to the point that re-threading would not fix the issues. Though heli-coiling is probably a viable option, getting a new crack set seems to be the cheaper/better option. I found a few options on ebay and just wanted some sound advice before making a purchase. I have a listing posted below. Is price reasonable? Anything I should ask the buyer before making purchase? I have seen some variants of Shimano 600 cranksets, does it make a huge difference which one I get? Is it highly probably that I will need new pedals too? Thanks in advance for any and all help!
