Should work just fine, Looking to upgrade to a LSD diff?

thanks for the info, i just need to replace the stock diff, my bearing and seals are bad and all new stuff is to much money.

If you look around you can find a LSD
This may help

Odometer will be significantly off, same for the speedo (and no, no replacement drive gear for the send is available for the W58 as far as I can find). You'll also lose acceleration, but your highway mileage will increase. Depending on how you drive in the city you mileage may suffer.

I ran a 3.91 from a pre89 GTE on my N/A for a while. I liked it for a commuter but I could definitely tell the difference when I opened it up.

If you're just trying to keep it moving, go for it, but it's not a performance upgrade.... If you just want a LSD then find a 4.30 LSD from a N/A.
