Given a choice, I'd prefer it in the main text, so that if the poster is asking about a different vehicle, there's no confusion.
Yes, would be nice if every time someone asked for help, they would not assume that every GMT400 is EXACTLY the same with EXACTLY the same engine and EXACTLY the same transmission. I run in to that all the time on TYF.

I belong to a couple of firearm forums and a poster never mixes up their Glocks.

In the future, it would help if you put your vehicle info in your signature and then update as needed. The GU6 is the 3.42 gear ratio, same as my 2005 Tahoe Z71. I do like the 3.73 gear in the 90 K2500 of my girl's. The 3.42 is a better highway gear for mpg. JB6 is the disc/drum vacuum brakes rated for up to 7200 lbs. GVWR. Again, my girl's K2500 has the same GVWR rating brakes.
where do i go to update that?
