I spoke to Aaron at FWC - they have the brackets, but he said if I have a rollover couch to just use the brackets off of them. I haven't looked at my couch yet because it's been raining for over a week here but it does make sense that the brackets would be the same. I can order the seat bottom cushion and back cushion from them but really pricey at $163.00 and $153.00 each. Ouch!! I'll have to put some effort into finding an upholsterer that can just modify the existing cushions that I won't be needing.
My 2002 did not have roll over brackets, there was a pull out and you put the back on it to make the lower bed. On the 2002 I cut down the foam and plywood base on the bench to make my cushions. Good friend cut down the covers for the cushions. I did not use a roll over bracket on my 2002 Hawk. I used ski poles and brackets to hold the seat back, you can see then in the video of my 2002 Hawk. Roll over brackets are much better and the way to go.
