I've been thinking about it for quite some time - removing the back seat to make room for a second spare, a bit of fuel (yep!

) and a few other doodads, but there just isn't a cargo barrier to be had for less than the price of a full set of tyres really.
Anyway here it is, made from bits of the old chook run, with $32.00 worth of plastic capping from Clark Rubber.
The white bit is plastic sheet to stop chafe on the gerries when they are loaded. I've made a floor insert to cover all the brackets and things, more on that later - it's not carpeted yet cause Bunnings closed today.
1) with seats out, there seems to be an awful lot of spare real estate in there:
2) Seat mounts looked like the logical place to begin, but of course the studs weren't particularly easy to measure, I ended up building a template from plywood then poking it round till it seemed to work.
3) My son in law kindly took my bits of ply and a few scratchings on an old message pad, and turned it into steel. When he arrived with it yesterday, he came with a bootload of files, hammers, grinders and a welder, but just to disappoint us both, the rotten thing just slipped into place like a bought one!
We couldn't work it out at first, but figured that because I'm right handed and he's left handed, my measurement errors were probably cancelled out by his fabrication ones.
4) Finally with a bit of plastic edging and some paint on it overnight, it's all ready to have the second spare bolted to it, and to do a heap more work I reckon.
We kept it at seat height deliberately, as we don't load higher than that under any circumstance, and we tie the lot down under a cargo net custom built for the job.
Notice how Mr Suzuki has left a nice little square edged recess in the floor to make it easy to do a floor insert over all those nasty exposed bolts.
I'll post a few more pics in a day or two, once the things all loaded and ready for business.
Cheers,
P
