I run a Lajoie custom seat I bought used a few years ago. I absolutely love the seat, it fits me perfectly. They only drawback was mounting it in the car. Its about a size 16 by normal standards with about a 20 degree layback. This seat was originally designed for a modified, not one for a smaller legend car. They are a little bulky compared to some but from a safety aspect I think they are the best. My seat had a box around the shoulder blade area with recessed mounting holes. I was not able to use these holes as they didn't line up with the mounting brackets in the car so I had to drill through the seat. On the bottom portion of the set I had a friend make up a mounting bracket made from square stock and tabs that bolted up to the existing mounts on the floor.
If your having Randy build you a seat tell him what its for and they will build it knowingly of the vehicle. If you can actually make it to him and have him fit you in his jig then even better, otherwise You will have to take your own measurements assuming you are doing a custom seat? Some guys run the "Saturday Night Special" model.
Really take you time mounting it in your car. It can be a struggle, some swearing, some in and out, maybe a beer or three. It tokk me a few attempts to get it where I wanted to. IMO Randy is the best out there. Make sure you get the angle of the belts correct, whether you are going over the top bar in the back or under. Any questions send me a message.
Best of Luck!
