Suzuki 4WD Club of Victoria

Hi guys,
I am currently trying to rebuild a Suzuki Sierra wide track hard top 1988 build which is a wide track.
It’s rear differential housing is bent and diff centre and driver’s side axle spline stripped. I am having no luck finding a replacement and was wondering if there are any aftermarket options available which are the same ratio and width? Would mid 90s coil rear end be an option?
Any thoughts/ suggestions appreciated.
PS Some in WA but they are not cheap and post from over there will add to the expense. If I can get them to post it?
Regards
Bill.

I have a bare WT Rear housing here, no axles though

The WT Housing would be a good start. I know someone who might have diff centre parts and axles so may be able to stick to original spec?
Thanks.
