The hardest thing about replacing the shock towers/engine compartment panels is making sure you have all the panels at he right height, angle, etc. I tore out the radiator support and the front apron on both sides and replaced them. Doing the shock towers would have been very simple at that point. It will be much more difficult for you, since you won't have the aprons out. Hope your friend does a good job! Good luck!
Here's a pic of my '69 when the front end was all torn apart.
