This is a great replacement for the stock OEM convoluted, plastic bushing contraption, that AMC/Jeep came up with 5 decades ago. I have a 98' NV242 and it shifts very easily, the knuckles are rust free aluminum, and the mounting bolts can be replaced with Stainless steel, coated with grease or underseal..
All in all a good replacement, and seems worry free.
You can probably fix your OEM for 30.00, but will not have the advantages and easy maintenance of this kit.
