Finished up my Tremec 5 speed project yesterday. All is well. Had it up to about 90 mph on the highway and NO vibration. The tranny tunnel really didn't need to be cut out as much as the dealer told me, but... I made due. Everything came out good, fit wise ,carpet, console, shifter, maybe an inch or so taller than it was before due to putting the 'Lid" back on after the cut out. Happy to get that behind me. Having a 5th gear....sure is nice
