smaller chainring where the big one used to be, then use the nuts n bolts from the kit to attach the smaller chainring, you cant use the old ones cause theyre to long, sometimes the
rear wheel needs to be dished out a bit so the chain can line up with the front chainring, if you know how to do this yourself your ahead of the game

add a chain and thats about it

I keep both the
front and rear brakes as long as they are functional

the rest is up to your personal preferance

Im sure if I missed something someone will be nice enough to tell you

any other questions feel free to ask

Did you even read the original post?
The guy said that the only thing that's not rusted and/or useless is the frame.
My two cents to the OP: See if you can get your $25 back. Why?
- If the frame is all that is usable, then you paid $25 for an old frame PLUS the thrill of removing all of the parts. You can get a basic track frame for $100-200.
- It's safe to say that if the rest of the bike's components are rusted then the frame is likely rusted, too. Frames can rust from the inside-out.
- Since you will wind up building a bike from scratch, why not start with the frame you want? It's sort of like, "Hey, I got a great deal on a piece of land. It's in a sh*tty neighborhood and I get to demolish the old house, BUT I'm going to build a great house on it!" Then what do you have? A great house in a sh*tty neighborhood...when you could have built that same great house in a better neighborhood for $100 more.
