How-to Swap the Motor Mounts?

[VetteMed]

I have been wondering if the lack of clearance between the #1 header tube and the steering shaft is due to sagging mounts, being that my car has a lot of miles on it.

I should have changed the mounts when the headers were off, but I didn't -- so now I'm left with wondering if I'm going to need to pull the headers off in order to change out the mounts or not. Does anyone know if it's doable with the headers (Jeal) in place?

Edit:
It's not doable. Pulling the headers is really not that bad of a job, and it gave the access needed to do this job properly. See later in thread for pics of mounts and more commentary.
