Ok so, i installed longtubes on my car not too long ago, got my exhaust made and what not, but sometime when letting out of the clutch to take off i can feel a solid knocking on the bottom of my car. at first i couldnt figure out what it could be, but i had to get back under my car so i got to looking and right above and towards the passenger side where the driveshaft goes into the transmission, theres rust marks and dents from the driveshaft. what could be causing that suddenly? trans mount shot? possibly the torque arm bushing? whats your input?

Trans mount.

thats what im pointing towards, maybe additional torque also with the lifting of the motor with it bolted down to get the long tubes in place stressed it to the breaking point.
