Inatalling Diamond Plate Rockers


I bought some diamond plate rockers for my cart. They look easy enough to install...WRONG! These things are the biggest pain in the A$$. Has anybody else had trouble with these? For the life of me I cant get them to sit right with the body. There is about a 1" gap between them and the rear body. Also they give you plastic plugs that insert into the side rails and screws screw into it to support the rockers on the side. Every time I start screwing it they pop out! :wallbash:
They say these install in minutes...I have been working on this since 9:00 this morning and its now after 7:00. :D Does anybody have some pointers to give on installing the diamond plate rockers on this EZGO before I take a sledge hammer to the cart? Thanks
