I've just bought a swivel plate but it there is no base for it to bolt onto, had a look around on the wiki and the forum to see if anyone has fabricated something for the plate to sit on but only found a reference to 'plate 19' (see below). I have plates 20 & 21, no idea whether you can get number 19 anymore, assuming not.
Can some one advise me on what to do?! Under the seat at the moment is just a large hole (no battery on passenger side) and the original rumers.
Thanks in advance.
