Ah, you're stealing my idea!
LOL! I don't think there'd be too much to this. I got a new book at the store the other day with all kinds of air ride seats and they were pretty reasonable too. They even offered a little 12v compressor in case you didn't have air on the truck. Like Bcfast just said, it looks like the trick is to be very careful on measurements but I found some in there that looked like they would fit ok. Let's face it, with some of the other hoops we jump through to modify our trucks, I bet this one wouldn't be too bad. Whenver my seat wears out, I plan to try and bolt some in. If you need any more info, drop me a line.
