Ha just looked a bit more and read the thread… Yours has the correct 6cyl cab floor and engine cover and wheels and obv is a dual rear so , is def a 550fg…

Hey mate just happened upon this thread-suddenly been a bit of FG activity in NZ (the deals on wheels tow truck resto and the awesome race transporter) and the duck island truck-all of which I missed being distracted elsewhere last few years. I have factory workshop manual I’m happy to get you a copy of, though they are pretty basic and logical to figure out. I bought a couple of these back in the mid to late 1990’s off NZTS, (now alsco) who ram them as laundry trucks up until 96 when transits took over. The ones I purchased had been converted to Falcon 250’s with 3 underfloor CNG tanks. Could go AL to Welly for about $50 with a $26 fill in Taihape. one long gone I’m in the protracted restoration of the other-need to stop procrastinating and building other cars and finish it… single rear axles. Yours almost certainly started life as a 4cyl, 2.2 (or 2.4 if it’s 74ish or later which is unlikely) and likely ratio is 5.9:1, I swapped 4.58:1 rear crown and pinion into mine, and they are a v strong rear, but the options you mention would make it a lot easier. Badges on side should be 360FG 350FG, or FGK30. This is the model dual wheels were on the Fgk40 upwards which also had the 6cyl Austin donk, through to the FGK100 which were usually big diesels.
