I know some guys who would go to a tire shop and the shop would give them a bucket or two of the balancing weights that they took off when they would change tires. Try there.
Bad1 Just wanted to let you know that the weel weights have some tin in them. It seems to clog up some of the melting pots. It also makes a lot of smoke when melting it,so make sure that you have a good ventalating system when melting.Best of luck. Scotti G.
