I like 2016-19 Silverado too; however, I just want to caution you before you are going to do it. If your 2014 Silverado has part of front end damage that needs few parts replacement anyway or it has a rebuilt title then I might consider do the conversion. Other than that, 1) if you have a clean title, you might have a hard time convincing a prospective and suspicious buyer that your pickup has all original part and paint or has never been in an accident. 2) your 2014 parts have used resale values. 3) unless the 2016 parts are real cheap, I would use the money from not doing the conversion to lift/drop with a really nice set of wheel and tire plus other modifications to make your 2014 uniquely your. Someday, who knows you might get bored with your 2014 then you might consider 2023-2025 generation looks. In my opinion, think twice because it might not worth it.
