Reese dual cam problem

I am hooked into the seventh link have two links hanging free. New bracket I got have one bolt instead of two but single bolt is mounted much higher on the hanger bracket than the two bolts that were in the bottom of the old hanger brackets. Trailer is tucked away and cant get it out and hooked up till Monday after graduation party we are having here for two grandkids on Sunday. We leave on Tuesday so I will just have to keep an eye on things again the setup has been the same for 3 years with first trailer and two years with existing trailer. Usually kick off bars if going to have to jack knife trailer when backing in. Only thing different this site was no jack knife but very steep incline backing in then trailer leveled off and truck still on steep down incline. Will try to post pics after I get it out on Monday.
