Just use a couple of blocks of firm foam about 2x4" and a foot long.. Not the squeeky esky foam.. or just use pool noodles.. Put the flat board upside down on the bottom (nose forward) and curved board also upside down on top (also nose forward) .. That's what I'd do.
You can't see my foam blocks I this pic but they are there between my 14 and 17' Glides.
