Well i have everything on order. I got the connector off of ebay, a new IAT sensor and harness from summit. I picked up the IAT sensor just incase i dont like how the IAT sensor response in the new MAF. I got all the couplers and tbolt clamps coming as well.
The u-build-it tube showed up the other day. It is 4in outside diamter which is kinda a bummer. You can see the inside width below. I will say this about the tube, it is THiCK ABS plastic so that is good.

Here is the pinout for the MAF incase anyone is interested. The sensor is labeled so it is pretty easy swap
MAF part
Pin A yellow - MAF signal to ECM
Pin B black/white - ground
Pin C pink - ignition 1 voltage from fuse block
IAT part
Pin D tan - low reference from ECM
Pin E tan - intake air temp signal to ECM
