tFUnk,
If you want to simplify things for the future you can replace the quill stem with a quill to threadless adapter that installs the same way as a quill stem, then use threadless stems with the two screw bar clamp such as you apparently have on your other bike.

There is nothing wrong with quill stems, but I am often swapping bars or stems so this type of setup works better for me.
Regards,
Raymond
