I can give you exact measurements of mine for you if you like. I have the fold down option as well.
Is your's a standard seat? (your earlier pictures are gone from the thread) If so, please measure between the sides at the frontmost top. (kind of in front of the ash trays) Thanks!
My interior is deluxe. My sides are out of the car. Do you want the measurement when they are installed (just woke up...still a little doppy)?
