1977 Triumph TR7 Race Car – Floor Surgery

We need to make more room for the driver’s seat in this race car. It needs to be lower to the floor for headroom and safety. The original seat mount position was strange and as you can see in the lower right of the first picture, the floor was cracking due to stresses from the seat.

Carefully we drilled out the spot welds on the original Triumph seat bracing, then carefully chiseled out the pieces. As you can see, there were already a significant number of holes in the floor along with some stress damage. We can straighten everything and fill every hole, but the faster option will be to fabricate and section in a new rear half of the floorboard.

We carefully marked the initial cuts of our tunnel modifications and removed the metal. There is a structural brace in the tunnel that is interfering with the cuts which we’ll have to deal with, but it will be an easy fix.

Once the initial cut was made we test-fit the seat. Once we deal with the brace we can be in a good position to test-fit the driver and make our final plans.
