Technical 28 A roadster floor panels

Hi, does anyone have measurements for where the front of the seat riser goes. Measurement from a-pillar (doorhindge post) to front of riser. I will try an load some photos of what i'm dealing with. Thanks

Why not just put it where it works best for you?

 

Thats too logical !! I thought i would find out wbere factory was an work from there .

 

If you'd like to be more logical cut that big hump thing out of there too. The original seat will put you sitting on top of the car rather than in it with no leg room.

 

making my own seat and using the riser for the base. That other big hump thing is only there to try and find out where the factory position is. I have the original seat and your correct - it is huge !!! planning on using plywood/old seatbelts and some foam.
