I'm in the process of recovering my seats. The fiberglass passenger bucket has three holes on both sides of the base. Does it bolt directly to the floor? No brackets? I can't remember how it came out of the car. Seems weird to bolt it directly to the floor?

The fiberglass base is held to the floor by (4) small studs on the floor pan and 2 small bolts on the cross member. Here is a 6 with the attachment points circled.
I believe both are M6 fasteners as I recall.  Attached thumbnail(s)

Directly to the floor. I just put mine back last weekend. @aturboman memory is correct. M6 nuts qty 4. M6 x15 bolts qty 2 (900 075 193 08). Plus washers. I think you will want to place your vinyl floor covering for the tunnel, door sills, and front seat rail before you install the backpad or seat bottom. |

I believe there is also a small 2 hole plate that helps hold it down on either side.

Our car didn't have hold down plates, but it doesn't mean it wasn't removed and lost. Here was I took out of our 1970 914-6.  |

No hold down plates on the early seat base. Even though its fiberglass, there's no torque on the seat bottom from acceleration or braking. It's just sitting on the floor and held in position with the studs.
Flat washer, lock washer, nut. |
