'89 lsd

OBX requires a rebuild out of the box to replace shitty hardware.

A CLSD from an 89 will require a rebuild if you want it to lock decently (new clutch plates can be had).

I would go for the CLSD out of an 89. Make sure it is not a viscous type.

I mainly want it for street driving, no track use. Is 300 a good deal? Should I have a shop rebuild it before I swap the unit?

Also, I have an '86-T 2+2, my rear end should be a 3.54, and '89-T's should have a 3.7, will it be a big difference 0-60, or highway driving (do almost none of that here)

$300 is a very good deal if it isn't beat to shit. They regularly sell for $600-$700.

300 is a great deal. Even if it is beat to crap, you can buy new clutch plates from Gary Savage for ~$100. Just gotta open it up and drop them in there and you'll be set.

If you are rebuilding you can always swap in the 3.54 Ring and Pinion but personally I would keep the 3.7.

I would rebuild with new clutch disks, bearings and seals. Might as well keep it fresh and new.

I'm going obx helical but if I had the option I'd get the clsd.

Thanks you just saved me time trying to remember where I saw that lol.

I would be all over the '89 LSD for $300 !!!!!!

I'd pay almost that much just for the finned cover. :P

so, $200 shipped for clsd, but 4.6 (200zr auto) is awesome deal?

Bad deal, let me get it.

man, this set (diff and axles) located at Vladivostok (Russia), shipping will be veeeery expensive, excluding ground (sea) shipping, but I think gear set will be for sale (clsd and axles will be inserted into EUDM case with 3.54 ratio)

well, I also get for $100/shipped 200zr hood (not only scoop, assy) and 200zr auto 7blades dual speed fan (OEM set actually -1 4blades dual speed, 1-7blades dual speed into oem bracket)
