Starter brush kits?

Who sells the cheapest starter brush replacement kit for an '82 KZ750 four (4 brush)??

I see them for about $40 up, but they must be cheaper somewhere.

Around $40 is what I have found is the going price.

Get it from Z1, I just put a set of theirs in my 4 brush starter. All fit and done in no time. Order some oil filters, or some other stuff at the same time to average out the freight a bit. Look at your bike and buy something else at the same time, they sell new batteries.
