Just found this thread. First of all, good on you for being able to straighten it out. Tells me I picked the right alloy! Secondly I'd like to comment on the fastening. This is the first one I've seen this happen , but icing left unchecked can lead to this. For most riders this is never a problem. It is imperative to look and inspect your sled if riding in conditions where progressive ice build up is a problem. This is not limited to skid plates. It pertains to tunnel,skid, nose area of sled etc. As mentioned before in other posts there are methods of further fastening of the front area of my skid plate if desired. The very front of it can be bolted to the subframe cross tube if desired. Even the sides of the skid plate on the front half of the plate can be fastened to the subframe tubes. I have been running my personal sled for the past 4 seasons with 4 1/2" holes in the subframe tubes in this area with no ill effects. Rivets were chosen to fasten the mounting tabs on the front for a reason. they can easily be replaced by nuts and bolts if one wishes but then something else might have to give. Ice can create extreme pressures. I think the best lesson here is to inspect your sled regularly.
