This may be old news to many of you, but I just replaced all 4 motor mounts on my '72 and shifting is much improved. Not perfect, as new synchros are in my future, but certainly a much surer feel to the shifts. I thought new mounts might make a difference to the feel of this car's shifting, and I picked up a trend in threads about motor mounts here and on the bird that seemed to indicate as much, so I'm just adding voice to the data base that it sure helped in this case. HTH
