? for those who use EAI X-airs

First for those who hate EAI let me say I love the X-airs. I just installed the x-air cylinders and brackets on the front of my car over the weekend. While driving the bottom bolt backed out and I lost the bolt and washers that hold the bracket to the cylinder shaft. The car is still drivable but I called EAI and they told me not to drive it and that I was supposed to use locktite on the bolt but the instructions that came with the cylinders didn't say anything about it I guess I should have called them, but they said it would be $68 to overnight a new set of the washers that have the bearings built in to me. Did any of you have problems with the bottom bolt and washers?
