I do like Marc, and I lift the manual top up a bit to get it in between the top of back rest and top at corners....
So now I am wondering if there is a difference with '69? Perhaps '67-'68 had the problem with them blowing out, so they changed something? I just looked at my '68 again now that I am home, and there is no way that boot would go in between the seat and frame the way you guys show. Maybe post a pict of the seat top without the boot in there so we can compare.
I used to be indecisive. Now I'm not sure.
