mad max, mine is a 64 high hump, should be about the same as yours. I also received mine from stock interiors as listed above and couldn't be happier. It fit great and the price was great.
Find attached a link to my photo bucket that shows how high up mine went. This was after I trimmed just a bit across the top edge.
I still have a ways to go but it is getting there.
