I have a 84 mustang with a QA1 mild k member ,a arms,coil overs and its getting a 460-C6 combo. the converter is a tci with studs you can unscrew. but with them in its not working do i need to get it toghether then put them in or maybe just start with one to line it up? do i need to cut or beat the hell out of the tranny tunnle at all? Or do i have to put in the motor and trans at the same time? it looks like the C6 aint gonna fit, the two top bolts have to go in first then they hit the fire wall as you go up with the trans.The motor mounts are from holcomb i bought them about 9 years ago well any input to get me on the right track would be a great help thanks.
