I fitted a bulkhead (plywood) today, i made it myself and firstly covered it in 12mm thick underlay matting for sound deadening and then covered it in black acoustic carpet.
I set the bulkhead back to allow the seats to recline and also to give me a little storage space behind the seats.... I covered the exposed floor with the same underlay and acoustic carpet....
(just got to trim the acoustic carpet once the glue has dried).
I also took out the headlining and painted it black to match the acoustic carpet....
The A pillar covers were painted black aswell...
Door cards are next on my list to do, get them covered.
cheers
Andy
