International D1610, "disc wheels" rear singles?

Hey Gents. Chasing info, parts catalogues, service manuals that may reference the D1610 trucks built with the "disc wheels" and singles instead of the duals. I believe they ran a spacer/adapter a[ch341]angement to convert from a 5 stud axle to the 6 stud wheel. The example that I have photos of has 10.00x20 on the compliance plate for tyre size instead of the standard 8.35x20.
I believe (possible mistakenly) that it was a CFS vehicle. Not sure what agencies bought them but I am eager for anyone who may have reference to them.[img][/img]

That should read "8.25

we had a 510A acco 4x4 with singles all round and it had a flat disc in the center it went on one way for the front axle and reversed for the back axle they was big fat singles like 15 inch 4x4 type tyres not sure on size now

I have the feeling that I'm going to have to find somebody with a service manual or parts book.

Did anyone end up having good info on this single wheel ?
Does anyone have a pic of the I'd plate. The photo bucket link doesn't work anymore.
Thanks

The only reference i can find to a spacer in 6/1974 D Line parts book, is on the front of D-1310 4x4 below chassis No. B04698. 
IH part number 883 270 R92, wheel spacer assembly, with studs.  2 required.


D-1610 4x4 is listed as using 7.50-20 tyres on 5 stud rim, IH part No. 850 217 R92.
D-1610 4x4 with 189"wb is listed as using 9.00/10.00-20 tyres on 6 stud rim, IH part No.4314 230 R91.

The spec plate above shows 189"wb.

The trucks with 10.00x20 singles were ex BMR ./DOI ......they sold quite a few of them ,bright yellow ,singles and a steel well type body with an army style canvas top..........they also sold D1310/4x4s s with singles ...my brother has one .........used to be one of each parked down the very end of Wynnum Rd ,near the refinery fence..........previously they also sold RLHC Bedfords set up the same way........Ron Thompson bought one and drove it to England overland ,in the days when you could do that.

The spacer listed for the D1310/D1410 is to adapt the front axle to dual (dished) type wheels........its not used with singles .........another feature of the BMR trucks was a tropical roof ,common enough on some pommy trucks,but Ive never seen them on Australian Inters.
