Ford Fat front seat and floor

[Harlé Sylvain]

Hello
And Happy new year!

Now that my doors are finish, I will begin the floor an the seat mounts.

I only have the right seat mount, the seat is welded on the floor ,but under the seats sliders, there are 4 pair of holes, where the seat bolted on the floor cover?

I think that the right seat floor could be open, but why? Was the battery there?

My last question, is the left seat floor similar of the right, could it be also open?

cheers
Sylvain
