Drive shaft question - Bagged SWB 72

[MattPSU]

Now that my 5.3 and 4L60E are installed, I started to look at measuring for a new drive shaft. My truck is a SWB 72 and it's bagged with cups/plates and Porterbuilt's bolt in notch. It originally had a 2 piece drive shaft and I was going to have a one piece made. However, it seems that it'll hit the upper part of the cross member when lowered. I attached a long 1x1 to the yolk and ran it to the rear end then lowered it and the 1x1 is really close to the upper part of the cross member when laid out. Is anyone else running a similar set up with a one piece drive shaft?
