Splitwindow Baseplate back cushion

To keep the cushion on top of the enginebay of the Splitbus nice and tight, we can supply this oiltempered hardboard underplate. Cut to shape if forms a perfect base to glue onto your foam. Tack the upholstery to it and finish of with some thick felt or undercarpet against engine noise.
Note that this is a bit smaller than the actual cushion to make sure the sides are not going to be visible throught the upholstery.
