Anyone still following?
If I remember the info correctly you can use the old bench riser. I don't think there is a "different" riser for another type of seat. This is my theory and from what I remember. I would advise you to check carefully as I have not yet done a swap and anything I write here is just something I have read. I have been looking into it as my bench seat is pretty crapped out.
My suggestion would be to go back from the beginning of the thread and print each page that appears to have info pertaining to what you want to do and put those in your "truck" file for reading by the light of a work light when your ass is freezing under the truck trying to turn a stuck seat bolt. Good luck !
