Throttle Body Inlet Elbow, another option

Throttle Body Inlet Elbow, another option I am getting closer to my swap and want to have everything on hand to make the process as smooth as possible. I searched high and low for a factory looking elbow that would transition from 3.5" at the MAF to ~4" at the throttle body. I refuse to pay $100 for the LT1 elbow and don't really like the webbing on the rubber and I prefer a more OEM look than a silicone elbow. Figured I would share this.
Hunting for options in the junkyard today I cam across this guy and after sizing it up, I took a chance. I think it cam off something with the transverse mounted 3.8l V6. The MAF looked just like my 2000 F-Body MAF, and it was nice and smooth with a bellowed section on the long end. In addition it was short and didn't extend much from the throttle body. Got it home and it was close to slipping on as is, but just couldn't motivate it on. Went into the kitchen, boiled some water and after a ~3 min bath, on it went. Let it cool to room temp and then pulled it off. It clearly stretched enough and I was able to slide it back on with the assistance of some silicone spray.
Going to need a new clamp at the throttle body as the original one is just too small. On the other end the MAF slides right in, clamp works great. The elbow is made of plastic (ends are rubber), so I am going to drill a hole and use a grommet for the IAT sensor. There is enough room on the inside of the bend to tuck it in nicely for a clean appearance. Overall it should work great and give a nice OEM appearance. Best part, I think it cost $4! Part # 25099974
Now for the pics.

That looks a lot like the one I used from a Caddy Northstar car at the boneyard. Mine wouldn't make it on the TB either but softening it with a heat gun did it - needed to be about 1/2" bigger.
