Anybody put a 800 style tailgate cap on a 400? I read about this somewhere but can't come up with any pics. Seems like a good idea IMO! Pics please if there are any out there! Thanks!

i have a cap in the shop and dry fit it. i also have an inside cover on the tailgate. with the cover it looks pretty close to fitting but it has a concave shape and do not see it fitting without the cover. guess the only way to mount is 3M but not sure.
i will post pics if interested.

Its been done. I wouldn’t screw it down until you are sure. I don’t have any pics, but they don’t look too bad. The main issue I’ve seen with them is that sometimes they are warped. Not sure if the plastic is too thin for some of hotter regions to prevent warping, or if it was improper installation.

Personally. I’d go with an aftermarket one to match the bedside caps.

Can probably be made to fit. I might like it. Gonna take the one off my 800 this weekend and see how it works. Never know, might be the next super-mod! Lol!
Good luck. I tried, didn't look like it belonged. I held out for a GMT400 shell. Glad I did.

I want to see these so called installed pics from various angles.

A couple of years ago when I was @ the j/y, I sat one of these caps on a gmt400 tailgate. the gmt400 tailgate was thinner & contoured slightly different @ the top. Having the outside end sitting flush together left a decent gap on the back side. even after sliding a section of tailgate bed liner in & guestimating some double sided tape thickness, left me w/ a feeling of it getting ripped off during use due to its height, so I nixed the idea.

Maybe someone thought of something that I didn't
