did i damage my t-5? help!

[90dpscoupe]

Im worried, i was bolting in my new t-5 (newly rebuilt) by myself, it was hard, anyways, i bumped the tail part up under by where the 4 shifter bolts hold, and chipped a chunk of aluminum or alloy whatever it is small though, but now there is some black foam looking stuff sticking out, i guess i can j.b weld it, but can i live with it? cuz nothing can leak out there, im just worried it will make that one bolt that holds the shifter weak?

never attemp this t-5 install by yourself on a gravel driveway, i had hel1.
