1991 Ls400 Differential Bushings? Cant Find Anywhere

[flipmode64]

Searched and searched and searched and cannot find differential bushings for 90-92.

When I brake at highway speeds my gearshifter wobbles back and forth.

Should I be replacing those ADUS505 bushings first, car has 350,xxx km on it. Also there is vibration through gas pedal if I hold the rpms at 1200-1500, anywhere else it is smooth. I'm wondering if that it the U-Joint itself.

I read all this talk about people replacing diff bushings but its all the later years.

I hve a 94 donor car but I do not want to go through the hassle to remove the whole assembly unless someone can tell me if its a complete matchup from a 94 to 91.

Thanks

If the shifter wobbles, I would think maybe transmission mount?
