The material will be pre-formed to suit the cushion mate , you'd be better off with a bit of material non formed . It MIGHT not leave enough space to do an earlier model cushion
Damn, still cant find any of that gripper material, If I could I could do my own custom job, well I could cut the material and ask the old ladie to stitch it up, but the problem is finding that damn sticky vinyl.
I may have to ask a massive favour of you soon and send me some up.
