I had to replace my six-speed index chain in a hurry today... and instead of using the master link, I connected the chain by pushing out one of the normal pins and pushing it back in. I just realized my mistake, and I can't tell which of the pins it is that I used to connect the chain. Is this setup dangerous? Do I need to just scrap this new chain and put another on the bike? If it makes a difference, the instructions that came with the chain claim that it uses "specially riveted pins".

Thanks!
