2000 Dakota rear axle - limited slip questions

Thanks for all the Input people. I really appreciate it.

I got lots of prices for all levels of LSDiffs.
Then I called my local Dodge parts department dealer. Told them what I had and asked what it would cost for the factory set up. The guy responds, “ I actually have a factory Spicer locker on the shelf a customer ordered for a truck and never picked up. I’ve had it for about 5 years waiting for you. I will give you a GREAT deal if you buy it.” I said okay what’s the deal?
He told me $326.00 and would throw in the lube, friction modifier and rtv sealant for the cover.... delivered to my shop.
So even though it’s not a top of the line rock crawler locking diff, it will slow the tire wear on the right side. If this does not work than the 2x4 to the boy’s a$$ will be the next modification.
Thanks for the help!
