Hello Alfredo, thanks for reaching out. I will need the model number and serial number from your cover in order to confirm the correct replacement cover. There is usually a sticker or tag that has these numbers on the driver side rail somewhere near the cab. Sometimes the SN or date code is printed on the bottom of the cover itself. Drop the model number and serial number in the comments below and I am happy to help find the correct cover.
