Here's a portion of my last parts ad I ran: 1973-80 GM 12 Bolt rear & Dana 44 front, 6 lug, rear needs brakes, 3.73 gears. GM 12 bolt limited slip rear & 10 bolt front, 6 lug, 3.07 gears, both complete, with locking hubs A guy called interested in them. When I told them they were 4x4 truck rear ends and 6-lug, and not car coil spring rear ends like he was asking, he said, Oh, that's not what I can use. Ok, so I didn't specify "car" in the ad for these axles, but everything surrounding these said "Truck" and 4x4... and wow, I did write plainly "6 lug". Another example of people who can't read.
