Try some aerosol gasket remover from an auto parts store. Be careful this stuff is really strong and even the smallest over spray on your skin will burn. This stuff will even take off silicone!
I have not tried to remove the adhesive, and I am not certain why you would feel like it was necessary? I have a '74 31' international that is gutted. I found that a shop vac with an upolstry attachment was amazing to get the smaller fibers out.
