Someone ID a Mongoose frame for me ?

[rexhunta]

Got this to put some stuff together for my cousin. As far as i can find, it's a mongoose. Can anyone ID a model so i can start finding crank parts for it ? As it is missing 1 of the arms, and the 2 other sets of Mongoose Cranks i have are a different pattern.. The end of the Crank has 8 slots, the arms i have, have about 12 or 14.

Thanks Pete

Seems like you need an 8-spline crank arm... unless you have any mates with old 3 piece cranks it cheaper just to get a cheap set from your local or go the one piece if its just a fun bike...
