need to redo my rear seat in my 25 tantrum,can anyone tell me how to get the rear seatback out.don't see any screws from behind?

Holes in the bulkhead plugged with white plugs on mine. Had it out a few times already cleaning it Use a socket that will hold omto the nuts so they don't fall into the abyss between the seat and the engine compartment.
.

don't remember any plugs there but i will look again

anyone have any idea how to get this seat out.no screws,plugs,anything on the backside

look between the seam of the back seat..you may find them there.

Oh yea...the hidden screws!! Thanks for the reminder Steve. You did learn something when you worked there huh?
