help with a motobecane

I was recently given a 70's 12 speed motobecane with one major problem: the front derailleur, shifter etc are all missing. I was just wondering if I could use an index shifter, derailleur etc from an 18 speed mountain bike to make it rideable am pretty new to bike mechanics but I am good with tools. I plan on eventually going all original but I don't want to let sit in my garage collecting dust until I get all the parts and have the time to do it.
Thanks in advance for all the help

Sounds like an excellent candidate for a single speed conversion.

If you try to use the mtb stuff, you need to check the location of the cable pull, diameter of the clamp, etc. You probably are better off getting some used stuff on ebay. Won't cost much if you are not in a hurry.

I bought a mid grade FD for a project on ebay for $10. I could have done better (paid less), but I needed a specific model to complete a group I have. I have bought complete FD, RD and shifters for around $15.

Of course, your mtb has a triple up front, your Motobecane has a double. Depending on your bottom bracket, you could have a lot of problems mounting that triple on the bike. And if you want to keep it original, that is going the wrong direction.

I'll probably end up going the ebay route just wanted to make it rideable for now but I'm guessing that the mtb stuff will just give me more headaches than it's worth to put on. I can always ride the '64 Schwinn....Ebay here I come
