<strong>Yahoo Message Number: 65431</strong>I have one switch that is cracked and will not permit the panel nut to tighten (that is the Jake brake, high - medium - low switch. I also have about a dozen broken plastic (or nylon) knurled panel nuts. I have spent hours trying to find the black knurled nuts to no avail.<br/><br/>Can somebody help me find sources of these?<br/><br/>Thanks, <br/>Les<br/><br/>2000 Magna 40 #5840
