1999 chevy 1500 2wd auto locking rear ???s
my truck is a 99 2wd silverado witha a 4.3 and an auto tranny, it also has a automatic locking rear diff, but i looked up the vin to see what the plant says it has for options and it does not list the auto locking rear, does this mean it was an aftermarket addition?
