as above thanks
? I bought a rolling chassis and if I post up a chassis number can someone tell me what year it would be..... or how I can find out?? It is a wt swb

[mrw82]

A WT SWB diff ratio will be 3.7
A 1litre has a diff ratio on 4.1

Confusion???

All 1.0 sierras are 4.1 diff ratio, regardless of year.

An 85 drover ute should be a 1.3. As a narrow track, it will have a 3.9 ratio.

All WT sierras are 3.7 diff ratio.
All NT sierras are 3.9 diff ratio.

1.3 wt is 3.7

1.0 is 4.1

Thanks for clearing that up shep and Gwagensteve
Have wt diffs to go into the drover and have a nt with a blown rear diff so was hoping to use the diff out of the drover
that won't work....
cheers

the nt with the blown diff is a 1 Lt so it is going to need a 4.1
