I would say that is entirely doable. I just built a late 70's Super Le tour 12.2 with 9 speed Tiagra this afternoon. One little hand spread on the drops, and then a flick of the wrist, and it popped right in. I can't wait to ride it:-).,,,,,BD

You "might" need a little longer axle, and maybe a spacer to keep it out of the dropout, but sure.
