Inquiry about Direct Factory Carbon Fiber Bucket Car Racing Seats

Hi, interested in buying full containment competition racecar seats . To comply with the rules in the racing division of out target marketplace (Speedway sedan racing in Australia) they need to have upper rear mounting points built into them around the shoulder area. I can send you a picture of an example seat if you provide an email address to send it to. 

Would you be able to add these rear mount points in with a M8 thread inserts? and what sort of costs would we be looking at to develop and produce?
