So the intakes are a 1" 90* with a male and female end. The male end goes into the barrel and I got a 1" inner diameter coupler thing. I also have 2 lock washers on the outside to get a good pinch on there. It is very secure but will be even better when I tack weld it this week. Then there is a 12" pipe that threads into the 90* and the ball valve goes on the other side. I will not tack weld the ball valves on the top of the pipe. I also put a u-bolt around each so that it keeps them from moving.
I also have amazon prime but I didn't want to wait a couple days for the parts when Home Depot is literally right around the corner from my house. I was originally going to go with a 2" ball valve but they don't sell it and the ones on amazon were pretty expensive. After finishing it up, I actually like the look of the 2 intakes going up. I would also have had to buy a new adapter for my BBQ Guru because I only have one for a 1" and a 1.5" ball valve.
This is what I am going to use for the rack. It isn't this exact one but same concept: http://www.homedepot.com/p/Unbranded-ShelfTrack-84-in-Standard-Bracket-2812/100194576?N=5yc1vZc89d
Thank You Sir. We only go to town 2x a week so getting things delivered to my home is usually a bit quicker.
