the fitting were not the

"the fitting were not the same as what i had the curve was longer than the one in the truck so it took a minute to adjust to get them to work but got that one so the other side had a longer hard hose than the one in the truck i had to remove a bracket attach it then wedge the bracket back down beside it but they will get the job done and seem to function great"
