Single Speed Free Wheel

[Bill]

Ok all you BMX'ers, pro mechanics, and such I really need some help on figuring out what to replace this with? It is a Chinese made Single Speed BMX 20" freewheel. It has 18 teeth and I am assuming that it is the standard chain size. Anyways I was looking at something like this..... http://www.amazon.com/Shimano-18-tooth-freewheel-x1/dp/B001GSOJB6/ . Is that the size I am needing? Here are some pictures of how I took the freewheel off of the 20" wheel using what some call the "destructive method"! Can tell you the 1/8" bearings in the bottom and the front literally fall out when it is taken apart deeming it unusable again. I used the Park Tools Red spanner to remove the cap clock-wise. The rest of the body has to be in a vise and turned by using the wheel.
