You will find they are more than adequate, not unusual to find 60 year old trucks running on their original mounts. The front mount is the hard one to find parts for the only piece in reproduction is the rubber. The early trucks had horsepower ranges form 90-135 by the time you get to 261's and torque in the 180-200 ranges so they do the job.
