Hi- I'm 6'2" and in order to fit in my 911 with proper clearance I have bolted the seat brackets to the floorpan. To do this I removed the standard L shaped brackets welded to the pan and the raised trans sill (inner bracket) and the door sill (outer bracket). These pieces are shaped like an inverted L in position.
I'm not very comfortable with this arrangement given the thinness of the floor pan even though I'm using large diameter bolts and large washers to secure the brackets to the pan. I'm thinking of welding an L shaped piece to the sill and the pan and drilling through it to provide better support. This piece will be a non inverted L that fits flush agains the sill and pan that provides better support to the mounting area on the pan.
Any better suggestions?
