Call and ask them. All the ones I've seen have the 2 snaps which hold them to the floorpanels just in front of the seats.
The ones I got from England in 1990 didn't have a snap up at the top of the firewall end because it depends on the model you have. Mine is an early TR and had a center top snap up front originally so I had to put a new snap into the rubber mat to hold it up there to the base for the snap which was secured to the firewall in the footwell.
For a later TR3A (post 60000) and TR3B there is a clip that is secured to the firewall and holds the rubber mat up by pinching the top edge of the mat in the center so it doesn't need a snap here.

Front Floor Mats (cars after TS 5089) - Cars built after TS 5089 had the front footwell carpets replaced by
black rubber mats which fit the car in the same manner. these are not to be confused with the aftermarket
"Amco" floormats, as they extend up the bulkhead instead of covering only the floor.
- On cars having sloping rear shelves (pre TS 60000), the rear heelboard side pieces were usually glued, as
was the arch shaped center bulkhead panel. The propshaft tunnel carpets were glued, screwed, or left
loose. The transmission tunnel carpet(s) were snapped. The side bulkhead carpets (kickpanels) were
screwed along the dooredge, and glued or screwed at the front. The rear floor carpets were left loose, the
seats holding them down. The rear shelf carpet was most often screwed.<span style="font-weight: bold"> The front footwell carpets or
mats snaps at the front, on the bulkhead. Often, these front snaps are replaced by blued jawed clamps,
particularly on later cars*.</span>
NOTE: TRA does not define "later cars". However, my car, TS58476 LO, built Sept. 1, 1959 has always had clips rather than snaps to hold the front rubber mats.
Input from other 3A/3B owners, regarding this detail, would be appreciated.
