I can not get the video to open for me so I will go with what you see due to my total lack of knowledge of the Foxbody platform.That vibration indicated by the shifter doesn't look all that abnormal really. I drove many foxbody mustangs that were like that. Urethane mounts, urethane bushings or solid rod ends on suspension parts does that real quick
More than likely Danny will take good care of that 351w...so long as the owner doesn't try yo go too cheap on internal parts lol.
This all keeps reminding me that we have to have ours freshened up at the end of this season. Not looking forward to that
