Concur with the suggestions above..AND the truck mount hardware can be a PITA to install...I had to add another thru bolt to make mine stop rattleing after 10K...next thing The bracket for the underside of the cabover...make sure you find solid mounting place and if possible try to use bolts as long screws will work themeselves out and the holes become useless until you plug them and drill again...now here's the next thing: in my haste I forgot to unhook them when doing something to the TC and pulled the bracket off...so the screws just pulled out...so what would have happened if it had been bolts...damned if you do damned if you don't! On the rebuild I will install some good hardwood mountings in the cabover rails, but not reinstall the shocks until I have driven without them for a while...when I broke them I drove about 5000 miles and didn't miss them to got back home...so for me it is a toss up...maybe they are worth it maybe not...GOOD LUCK with yours I hope it helps with the situation you experience.
