im new to this....i just purchased the riva top-loader intake grate and im having a couple of issues taking off the stock one...i took off the old grate which was four screws but then there is another plate that has four screws to... does that have to come off and no its not the ride plate, because i tried taking off that plate next to the intake grate but i removed all four screws and its a little hard to take off. it look like it stuckon there with silicone or something... does that get puller off?? thanks. i will post some pics
