99-06 seat 40/20/40 measurements

[Nitis]

Can anyone who has installed these make some general measurements that I might be able to use to determine how much space I am losing

Really wanted a 95-99 60/40 but they are getting hard to come by and are not easy to recover.

I'm aware of reinforcement of seat belts that would be needed for seatbelt reasons. Just looking for measurements. I'm a bigger guy 6'3" 240

I'm thinking floor where base boots down to top front of seat. Where your thigh is.

And some how distance from the back to the steering wheel
