I have a 90 Galant GSX and found a 1G VLSD 3-bolt rear I want to use in the car. The GGSX has a 2.846 diff ratio, the VLSD is a 3.545, can I swap this into the car or will I need a matching transmission from the 1G dsm also?

I'm used to working on 4wd's with conventional front and rear diffs where you can't mix ratios unless they're close like a 3.83 and 3.86 or something similar. I don't know how the torque distribution works exactly in these cars, will center diff/trans adjust at road speed or will the tires be fighting to turn different speeds?

Any help would be greatly appreciated.

Thanks.
