Feel free to call me. I will look for my paperwork on the seat. The seat I purchased comes in a variety of different sizes. You take your measurements and send them to Butler and they match that to one that is closest to your measurements. There are a variety of accessories you may want that I can also share with you as well as how I mounted it.
I purchased the 25 degree lay back, rather than the 10 degree one as it gave me more mounting latitude and provided much more head room for my helmet, which was very important to me. A side benefit is that it gives me a low rider look in the car.
You will want/need a quick disconnect for your steering wheel however. To make sure I had lots of room to get out of the car window, I even added some spacers to the pedals to move the seat farther back too.
If you decide to go with this type of seat, I will be happy to assist with all the little things I learned. I put mine in three times to get what I wanted and can, perhaps, save you some effort.
These seats are the BEST with keeping you safe, in my opinion. The other part is a great harness. When it is time to get a new one, I strongly suggest a six or seven point one and Team Tec makes the best one I have ever seen so I bought it. They can re-web it when it times out for less than the cost of a new one and are great to work with.
Good luck with getting your car up to the place you want it.
