I have a split front bench seat believed to be out of a '72. I want the split center section to fold forward so dogs can get to the back a little easier, so planning on putting this in our '68. But the middle section won't fold forward>....there are gas lines coming from tank that snake behind the passenger seat and go up the back of the center "arm rest" section. Is this how all split benches are??? Seems crazy that there is what appears to be a center section that "could" fold forward, but won't. Any help appreciated!!!!
