Hi there,

Basically i bought an old Vintage Bike a few days ago, with the hope of doing it up and restoring it.

First port of call was removing the derailleur as the limit screws did not work in the very old derailleur at all. The derailleur looks as if it was a bolt on type.

I want a new derailleur, Hopefully this one - http://www.amazon.co.uk/Shimano-Tourney-Derailleur-RDTX35B-Bracket/dp/B007VBWTGE/ref=sr_1_2?ie=UTF8&qid=1433871168&sr=8-2&keywords=rear+derailleur

However, i do not know how to fit it on at all.

The picture of the bike is here... http://tinypic.com/view.php?pic=9fr8eb&s=8#.VXcgq89Vikq.

Any help would be great!

    The bracket that the new derailleur is attached to fits around the axle that you can see protruding through the dropout in the photo you have linked to, and is bolted to the drop out. See the fitting instructions in the pdf link below.

    The RDTX35B Tourney is a MTB derailleur, you need the Road RD-A050 bracket mount model or a similar type.

    Right,

    But have you looked at the picture. The frame dropout seems pretty short. If i attach the bracket to it... the brackets length will be longer than the existing frame. Does this matter?

    Yes I can see that the horizontal drop out is not very long and that you might have a problem bolting the bracket attachment bolt through it and still have enough room to seat the axle.

    Before you buy anything I would take the frame to your LBS and ask them if it is possible to drill and tap an appropriate size hole in the drop out so that you can bolt the bracket on, rather than bolt through the drop out. Might not be possible though, they should be able to advise you of a solution.

    How was the original RD attached to the bike?
