Thanks for the info on the rivets, it definitely makes sense. I could see aluminum rivets possibly having issues due to their soft nature. For some reason I was thinking steel rivets would have issues with rusting or something like that, I dont know, brain farting I guess.
Hopefully Ill have the sled back together this week.
Still no insight on the left side support. Im curious if these common buckles are due to pressure from the drive axle to the rear over structure, or the drive axle to the front skid mount..........
