I was looking at some new air ride seats the other day at a dealer. With the air ride down all the way the seat stands about 2" taller than the stock Dodge bucket seats. By the time you add enough air to not bottom out that would add another 3" to 4". For me that puts me to high in the truck. I am just a little under 6'. If your down in the 5' something range one might work.
Check out a set of Caravan buckets. Ones from about the same year model would be close to our buckets. I am not sure what you would need to do on mountings.
