changing the shifters
Ok, the 1985 Centurion 12 speed is coming along nicely now. It looks like I have some options with regards to the gearings.
Now for some shifting issues. It currently has Shimano 6 speed index shifters mounted on the downtube. I like to get these and fully utilize the 7 speed that I'm comtemplating.
My question is, will this fit and work.
My ultimate goal is to restore this bike to where it is functionally on par with current technology and yet still retain that classic and original beauty of the bike.

Those will work fine. I bought a few sets at that great price, too. I believe the main difference between these levers and the more recent 8 or 9 speed indexed units are simply internal notches beneath the black plastic covers. The 7-speed shifters will fit on basically any modern downtube shifter bosses.
One recommendation... If you have an older similar set already mounted, check to see whether the boss covers which you may have on the bike will fit these as well. For frames with smaller tubing than is the current norm, the "radiused" boss covers are now hard to find. The ones supplied with these shifters are flat at their bases, and therefore better suited for placement on fatter tubing. - But this is really a very minor concern.
Here is an example of the narrow radiused boss covers which best follow the contours of the classic narrow frame tubes. ~ Just a minor detail, but we should all remember to NEVER throw any of these away.
