James,
Assuming that the shudder to which you refer is a pulsating
brake pedal, I would suggest that you have the front brake
rotors checked for runout. (Trueness). This is usually an
indication of a warped rotor.
How much higher tyre pressure are you talking about? On my
'73, I try to keep close to the original spec. I feel the
ride is much too hard if you go too far over the recommended
pressures. I generally keep mine at 22-23 front and 26-28
rear.
As far as replacing the dampers, yes they are much easier on
the rear than on the front.
Cheers,
Doug
