This bumper is for the 2019 and newer body-style Chevrolet Silverado (1500-3500). I designed the bumper using real life dimensions, and didn't need to make any modifications for it to fit the ERTL model. At the moment the only model I have test fitted this bumper on is the ERTL silverado so I cannot confirm how well it will fit the upcoming Greenlight models. More variants will come in the near future!
