You'll have to make them yourself. 3" blocks for 6X-72 coil suspensions aren't marketed or manufactured that I've ever seen. Obviously you could stack a 2" & 1" block on top of each other & have u-bolts made the appropriate length.

That being said, a 3" block isn't going to really help w/the pro-touring 'feel'. It might give the 'look', but the axle that far above the leverage of the arms won't improve geometry or stability @ all which is the basis of a g-machine.

I would suggest 2" blocks max. Maybe we can help figure out a better way to meet your goal: How low are you trying to get your truck? What other parts do you plan to use?
