Tailgate suggestions

[rusted75 half ton]

I'm looking for a good tailgate,and am leaning towards the aftermarket panels.The only thing that bothers me is that the metel is usually thinner and fit isn't that great
I've found some online that interest me,first is from www.****************.com http://www.****************.com/cata...20Tailgate.htm
they say it's the same thikness as the origional.

Anyone have expirence with these companies and parts?Are the parts all from the same manufacturer?Don't mind paying alot if it's good quality.

Thanks
