So I mocked up the front suspension, and as I kind of expected, the steering was an issue..... The 1 1/2" crossmember drop put the steering in contact with both the frame and the lower control arms.
I ended up deciding I'd move the steering up 1 1/4" to gain the clearance necessary. The passenger side is nice and easy, but the driver side is a bit more of a headache with the steering box & contoured framerail around the steering box.
