I cannot recommend this guy enough:
Sullivan's High Impact Tuning & Performance -Auto repair & high performance upgrades
He's located in Plainfield, Illinois (Joliet) and I don't think I'll ever go anywhere else to have something installed. He definitely knows his Fords.
I was charged $475 for the install or something like that. You could probably try to find something even cheaper, but everywhere I went wanted a lot for the install or didn't even remotely seem like they had any idea how to do it. My 4.10 has no howling on deceleration, only a slight whine around 35-45 mph. A lot of it has to do with the rear end and the new bushings.
He also deals with SCT and a bunch of vendors, so he's good for tuning too. He did the gear install the same day.
Edit: You live in the north burbs though, this is probably 30 miles south going down I-55 from Chicago.
