What else to change while you are changing the heater core. Might as well replace it if you can while the dash is out, but what is it that should be replaced. But can't remember what else to change out.

Remove the entire A/C system. (Don't need it with a convertible) :bigthumbsup
Saves probably 50-100 lbs.

Relocate P/S pump to where the A/C used to be.
This will distribute the weight better.
