I have a 46, if you want an easy seat change Mark VIII seats will fit right in, the back seats you just unhook the back take it out, take the bottom out, set a 2X4 on its side across hump, level screw to stock board, the back you just hang on the 46 hangers fits right in. The front you have to make some risers to lift the seats a little drill holes so you can mount to stock holes and then just drill holes for inside by hump.
