I be interested in knowing as well. My wife is vertically challenged and has been looking for a solution to give her a little more height in the seat. Looking for something that is easily removable or transferable between driver and passenger seats.

 

Don't know this for sure, but I'd bet if you got in touch with folks that make seat inserts (e.g. P1 Designs, Rstrada, etc.) they might be able to figure something out.
