Well, I got the rear storage locker all mocked up. Way more work that what I had hoped but the result is exactly what I wanted.
So, here is the original, disassembled unit, ready for fitting new "wings" on it to fit the earlier chassis. Of course it is good marine plywood, used biscuits and everything, plus a pile of epoxy to join. I fibreglassed the upper deck and the biggest stress point (where the brackets that tie the unit into the rear seat belt bolts are located)
Little bit of sanding, little fooling around, fits like a glove. This was the easy part, the harder part was the cupholders... here is the finished, mocked up result. Note that the centre part will get covered in vinyl, so the white ABS that I used to fabricate the lower section of the finishing panel will disappear. I tried to get black ABS, but no luck.
It works well, note the two little divots right below the actual cup holder assembly. They are needed to allow the foot of the holders to fold all the way downwards, that gives some spacing to more securely hold the cup/bottle or what have you
Here the holder is extended, the feet fitting nicely into the divots.
