Faceplated 833 4 Speed

I've been talking with Brewers about a faceplated box and I was told they could ship me one out. Not sure if "they" do it or send the parts out and assemble themselves. I was told it comes with billet steel bearing retainer, steel shift forks, upgraded side cover with 3/8" bolts instead of the standard 5/16". 1st gear is still syncrowed. My only concern is downshifting on the highway. Any one have any experience doing it?
