Where are you? If you add your basic location to your profile it will be a bnig help.

where are you?

i though the 1000 ute was a 4.625:1 ratio.

My parts book lists the following
38300-18000 Diferential 37/9 [4.11 to 1] Sedan & Coupe.
38300-H1100 Diferential 37/9 [4,11 to 1] Option Pickup [ute] Y
38300-18100 Diferential 35/8 [4.375 to 1] Van & Pickup [ute]
38300-Ho700 Diferential 35/8 [4.375 to 1] Van Y
38300-15400 Diferential 37/8 [4.625 to 1] Option Pickup [ute]
38300-G0500 Diferential 37/8 [4.625 to 1] Pickup [ute] Y

The letter Y means yes, that this part number is interchangeable with the part number before it. It's the supercession number.
It looks like the passenger models came with the 4.11 to 1 ratio without any options.
The Ute & Van came with a 4.375 ratio as standard.
Additionally, the ute could be ordered with a 4.11 to 1 ratio or a 4.625 ratio, but i don't think that we will find too many utes with factory fitted optional ratios in Australia

Do ute diffs fit other 1000 models? Like coupes?

Also, off the topic, I spotted a 1000 sedan in Cairns today. Horrible cond, but at least it was on the road, sunvisor and all!!!

Down south of Adelaide is where i am, Aldinga beach.
I have no idea what gearing it is.., all i know is that its out of my old 69 1000 ute,. It can fit into coupe as far as i can remember, its just the brake line mounts that are in aa different position.. Cheers

you now have pm!

The diferences in the Van/ Ute rear axle assemblies, & other passenger models are relatively small.
They use a larger axle bearing to help carry the load better in these commercial models.
The lower diff ratios are also intended to help the poor old A10 to handle the load.

The ute rear axle housing should bolt straight into the springs of other models & all the diferentials will interchange within all the 1000 axle housings as they are all H145's The axle shafts are the same for all 1000 models

Using a Datsun 1000 Ute [B20] rear axle assembly in a passenger model [B10] is not the same upgrade as using the 1200 ute [B120] rear axle assembly in a 1200 passenger car [B110] as the only real change is in the load carying ability [bearing size] & diff ratio [lower], however, the diff is not suitable for use behind high power engines that are driven in a high performance mode.

P.S. The Datsun 1200 passenger model diff will bolt right into the 1000 axle housing to provide a 3.9 to 1 ratio.
