was just luck the two crank sets used the same spindle
check the bottom bracket size of the frame too , ns frame will probably be either mid or spannish size , and you'll need a bb for the spindle size on the crank set usuallly 19mm, but may be 22mm ,
as Rob says BMXC counterfit cranks sets are real good value , the stark crank set is a steal for the price, both have the option to buy with a bb
