Trufiber LG136 Carbon Fiber Chin Spoiler Question

[bceeezy]

I got this chin spoiler (https://trufiber.com/shop/mustang-carbon-fiber-chin-spoiler-2/) from another member here and finally tried to do the install this weekend; however, it doesn't look like the stock lower deflector/shield works with it. I'm pretty sure it's the same mold as the boss 302 chin spoiler, so will I need to buy a new deflector to make it work (http://www.tascaparts.com/oe-ford/br3z17626a)? Or am I in any way able to use the one that came on my 2014 stock GT (non-GT/CS)?

Thanks in advance!

I got rid of my deflector it was damaged and caused the car to shake at high speeds. removed it no shake I'm looking at the same lip! The addiction all started with the gurnny flap

I trimmed the front of my stock lower shield to tuck up in-between the chin spoiler and bumper. Not sure if a Boss 302 lower shield would work.... anything aftermarket usually doesnt fit well with stock ford parts such as shields.

Thanks all. Everything lines up pretty well, just not the lower shield. When I have some time i'll look into it and possibly trimming or buying the GT CS/boss deflector shield.
