Help with conversion
 

I'm rebuilding my old bike that has just been sitting and rusting away I'm at a tech. block as I'm not very experienced with fixed gears. I just bought this BB conversion kit

http://www.amazon.com/BB-Conversion-...=pd_ys_iyr_img

I want to know what are the cheapest BB, Crank set, peddles and 15t-14t rear cog i can get off amazon. After stripping it all down and repainting it and other parts I had to buy im short on money so i just need parts that will get me by for a few months.

I'm just unsure of the mm, and if I would be ordering the correct parts.
