parts for my kz1000 LTD

ok well i went to put on the headers and was missing a couple nuts. also the bike has a half circle 2 piece metal gaskets. they were all bent up and wouldnt go on. is there an alternative, or some new stuff i can get these 2 diff sets of parts from? i am sure i am going to run into a few other misc. items so stay on top of this thread. thanks

I believe www.z1enterprises.com sells the "Half Moon" clamps for the exhaust system. Don't forget new exhaust gaskets(good sized copper crush washers) I understand the Suzuki ones are thicker.

also redline cycle .com has parts. one word
