Boyd keep in mind if you modify those Kirkey seats the covers wont fit, the covers will need to be modified or get someone to upholster them and that can be expensive. I have some aluminum extrusion for the perimeter if you need it after modifying them, it's in 3' straight sticks. I modified some Kirkey 41V seats and went to get them upholstered and nearly fell over when I found out the price. I'm just sticking with the FFR seats until my money tree blooms again. Those Kirkey seats sure get you down and back in the car, a much different more pleasant, comfortable position. Good luck with your decision.
