Legendary 66 barracuda seats questions

You have to ask yourself, "Do you find raised bolsters to be comfortable?" If not, does what others see matter more than your own comfort?
Without the added bolster foam a bucket seat will be almost as flat as the bench seat. That is my personal preference. I find the tall bolsters confining. So my 67 B'cuda buckets, Legendary buns and skins of about 8 years ago, didn't get any added foam.
