have them on mine and they work good. Mine are the ones that are all SS (including the mounting parts - have seen some that have plastic mounting parts) The newer versions have a internal SS cable built inside the spring that connects the two mounts = keeps things connected in the wind = NO blow overs. The only problem I have had is at Border Crossings (Canadian/US) inspections - sometimes the officers open the lid for a 'look-see', than can't figure out how to re-close it? = being they want me to stay in the car, I usually tell them if they open it to just leave it open and I will re-close it after I exit the area. Have had this trailer for over 7+ years now with them and they have held up !!great!! (and yes, I bought a extra set years ago -from Oregon Trailers- and still have not needed them)
just now after re-reading the original message noticed the 'date' ?? ah-da

= ????? 2007 ???????? oh well = this is 'my' answer to the question being asked..... take care
