"Back lowered"?

Do you mean lowering the seat back so it won't show through the big back window? By sectioning the frame or by cutting the mounts somehow to lower it?

If this is about the seat not showing through the back window I can tell you for sure you want to do it if only because the Sun will absolutely COOK the seat. The originally seat on my truck had been redone in a chocolate vinyl at some point and it was so brittle it would literally snap like a potato chip on the top edge from the Sun.
