I guess the third member is still okay and only the rear axle housing is rusted? Got any piccies you can post of yer rear axle?

Yes...you can weld it depending how bad it is. You can try www.car-part.com and see who's got one that's close to you. The ratio shouldn't matter as long as the third member is still good.

 

Hi all

I looking for a rear differential housing fot a 1995 4X4 6cyl A09A
3.91 ratio.

Diff housing, or axle housing?

Either way, you could start by posting and check the For Sale/Wanted sections of Toyota sites like this. Also your local offroad club sites.
