Default '70 floor pan outside edge loose.. how to clamp?

Passengers side, outside edge along rocker is loose and needs re-bonding. I need advice on how to clamp it after bonding agent has been applied. Any thoughts besides the 2 ideas I've come up with?

1. Take 2 long pieces of piece wood, place 1 above and 1 below. Drill two small holes through wood and floor pan then tighten together with screws. Let dry and remove. This will leave me with 2 very small holes in floor pan. No big deal.

2. Use big welding C clamps to clamp seam. Welding clamps have to be big enough to go around rocker from the out side.

Pic 1: The seam
Pic 2: Final repair area then I'm done!! Purple stuff is Evercoat tigerhait...similar to VPA but much harder to sand.

Here's how I did it.

1. Sanded inside seam with 60 grit. Used flossing technique while reaching under car. Sand paper was folder in half so both surfaces were thoroughly roughed up
2. Area was thoroughly degreased and cleaned with acetone.
3. Area was dried with an air compressor
4. VPA Vette Panel Adhesive bonding material
5. Wedged V shape bent coat hanger into seam to 'open it up'
6. Putty knife to force VPA into length of seam
7. When VPA was visible a long length of seam under the car I knew there was adequete filling
8. Wood blocks placed above and below and secured with #6 screws
9. Set for over 24 hours. Wood block removed.
10. Fiberglass mat will be overlapped along length of seam (not done yet)
