Yes, beautiful car.
AOS replacement is easy and part is cheap. I would be prepared with transmission and engine mounts as well, but only if you confirm they are worn or bad. You can buy the 993 part and bolt it to the bracket to save money and replace just the bushing on the engine mount.
Ive heard the flywheel and pressure plate bolts should be replaced, and it helps to read what your mechanic is about to go through...check it out here:

Have you decided on which IMS fix you are going to use? Just curious since I am preparing to replace these on a couple of 986s and would like to hear the debate from you and others...
